Relative humidity measurement sensor based on polyvinyl alcohol coated tilted fiber Bragg grating

This paper presents the development and studies of a relative humidity (RH) sensor based on polyvinyl alcohol (PVA) coated tilted fiber Bragg grating (TFBG). The TFBG used was inscribed in-house using 255 nm UV radiation generated from frequency doubled copper vapor laser. The cladding portion of the TFBG region was partially etched with 40% hydrogen fluoride acid. Partially cladding etched TFBG was coated with thin layer of PVA using dip-coating technique. PVA among the class of humidity sensing materials enables the strong coupling of cladding modes of TFBG with surrounding medium humidity level. The transmission losses of cladding modes of PVA coated etched TFBG changes as the humidity level of surrounding environment changes. The developed sensor was studied for RH ranging from 45% to 95%. The average sensitivity obtained in the investigated RH range is 0.095 dB/%RH. The sensor shows good linearity in the two ranges 45%–75% and 75%–95% of RH. The obtained sensitivity was 0.045 dB/%RH in the range 45%–75% and 0.144 dB/%RH in the range 75%–95%. Maximum sensitivity obtained from the experimental result was 0.297 dB/%RH.

Laser plasma–chemical treatment of optoelectronic materials

In this study, elements of a new technology for the treatment of optoelectronic materials—laser plasma–chemical treatment—are investigated considering the splitting of diamond and sapphire wafers into crystals as an example. Copper vapor lasers and an ultraviolet laser with wavelengths of 510.6, 578.2, and 355 nm, respectively, are used in the experiments. The working pressure in the reactor is 1×10−3−1×10−1torr.

Thermal performance of copper vapor chamber with double-sided uniform radial micro-grooved wicks by laser fabrication

In order to ensure the reliability of high heat-flux electronic devices, vapor chambers with double-sided uniform radial micro-grooved wicks (DURM) are developed. The driving force model of the working liquid inside the DURM vapor chamber is established. To enhance the driving force of the working liquid, the condensation micro-grooves and evaporation micro-grooves of the DURM vapor chamber are fabricated using an ultraviolet laser and an infrared laser, respectively. In addition, the startup characteristics and temperature uniformity of the DURM vapor chamber and the effect of the depth–width ratio and radiation angle of the micro-grooves and the filling ratio of the DURM vapor chamber on its thermal performance are also investigated. The results indicate that the DURM vapor chamber could maintain good temperature uniformity. Both the evaporation micro-grooved and condensation micro-grooved wicks facilitate the enhancement of the thermal performance of the vapor chamber. The double-sided micro-grooved wick with a larger depth–width ratio and a smaller radiation angle improves the thermal performance of the DURM vapor chamber. However, when the radiation angle is lower than 4°, further reducing the radiation angle has little effect on improving the thermal performance. In addition, an appropriate filling ratio helps reduce the thermal resistance of the vapor chamber under a certain heat load.

ИССЛЕДОВАНИЕ МОРФОЛОГИИ ПОВЕРХНОСТИ И СТРУКТУРНЫХ СВОЙСТВ МИКРОПОРОШКОВ ДИОКСИДА ТИТАНА

The surface morphology and structural properties of titanium dioxide micro-powders have been investigated by scanning electron microscopy and Raman spectroscopy. The Raman scattering was excited by the green line of a copper vapor laser (λ = 510.6 nm) which operates in a repetitively pulsed mode. Powders, consisting of close-packed particles in the form of spherical particles of specified sizes (29-63 μm), were investigated. The recorded Raman spectra of titanium dioxide powders were characterized by an anomalously high intensity, which was associated with trapping of exciting radiation in the mini-resonators of the cells. It was found that in titanium dioxide micro-powders in mini-resonator cells ( photon traps), the effect of “combination opalescence” is observed, leading to a sharp (by 5–6 orders of magnitude) increase in the Raman scattering intensity within the powder. It was revealed that the intensity of the Raman line of optical phonons at the Eg1 mode (144 cm-1) is more than 1000 times higher than the one of the Raman spectra of TiO2 micro-powders recorded under normal conditions (in a cylindrical cell with a large diameter). The high conversion efficiency of the exciting radiation into the Raman signal is explained by the large value of the total path that the exciting radiation photon travels in the dispersed medium in the photon trap. The developed original method for amplifying weak Raman signals based on mini-resonators (photon traps) opens up great prospects for recording weak signals of secondary radiation of powders of important inorganic and organic substances, as well as for creating small-sized laser analyzers of chemical compounds necessary for solving many applied problems.

Treatment of medium-sized facial nevus spilus with a dual-wavelength copper vapor laser

Nevus spilus (NS; synonym: speckled lentiginous nevus) − benign congenital or, more often, acquired melanocytic nevus − is characterized by numerous foci of hyperpigmentation located on a light brown background with possible transformation into malignant tumors. Its prevalence is ∼2% among the general population. NS sizes vary from 2 to 10 cm in diameter, but more extensive lesions have been described. Patients turn to a dermatologist when NS is located in aesthetically significant areas owing to cosmetic problems. Surgical methods for removing NS are associated with a risk of scarring. The use of various types of lasers for the treatment of NS has allowed successful results. However, it is accompanied by adverse effects such as scars, postinflammatory hyperpigmentation, and relapses. Our experience in treating benign melanocytic skin lesions using copper vapor laser (CVL) radiation, which allows selective heating of the pigment and blood vessels, gives us grounds for using CVL to treat NS. For the first time, we describe an innovative method of treating NS with dual-wavelength CVL radiation. A case of NS (medium size 50×40 mm) located in the cheek area was treated in a 39-year-old fair-skinned patient with type II skin, according to Fitzpatrick. NS treatment was carried out with the following parameters of the CVL (Yakhroma-Med model, P.N. Lebedev Physical Institute of the Russian Academy of Sciences): average power 0.6–0.8 W, with a power ratio of 3:2, at wavelengths of 511 and 578 nm. The pulse duration is 20 ns, the repetition rate is 16.6 kHz, the exposure time is 0.2–0.3 s, and the diameter of the light spot on the skin is 1 mm. After six treatments, the color of the hyperpigmented area, dark macules, and papules were eliminated. The follow-up period was 24 months. Medium-sized NS treatment with CVL provided complete elimination of the pathological focus and provided excellent cosmetic results. No relapse was observed within 24 months after treatment.

Treatment of pyogenic granuloma with copper vapor laser radiation

Background. Pyogenic granuloma (PG) or lobular capillary hemangioma, ICD10 code: L98.0. appears as a single bright red or violet papule up to 20 mm in size, on the face, fingers, skull surface, arms, and intergluteal fold, as well as on the oral mucous membranes. Surgical removal of facial PG is not always possible due to insufficient thickness of the dermis. Treatment of PG with a pulsed dye laser (PDL) or neodymium laser (Nd:YAG) can achieve a noticeable elimination of the lesion but is reported to be accompanied by such side effects as purpura or scarring. It determines the feasibility of introducing into clinical practice the methods of laser treatment of PG using the radiation of a copper vapor laser (CVL) with a wavelength of 578 nm, which effectively absorbed by the blood.
 Aim. The assessment of the clinical efficacy and safety of the CVL treating PG.
 Methods. 26 adult patients with PG in various parts of the face, including the lips, limbs, and trunk, were included in this study. PG treatment was carried out in one session with CVL (Yakhroma-Med, FIAN) at an average power of 0.71.0 W, at a wavelength of 578 nm, exposure time 0.20.3 s. The diameter of the light spot is 1 mm.
 Results. Immediately after the single laser treatment, the PG involved area became grey. In 710 days, the irradiated area was utterly similar to the adjacent intact skin. No postoperative bleeding or infection was noted. Side effects included mild skin atrophy. During the follow-up observation for five years, no side effects were found.
 Conclusion. The high efficiency of PG elimination using CVL in the absence of pronounced side effects allows suggesting this method for introducing into dermatologists and cosmetologists' clinical practice as a highly effective and inexpensive method of treatment.

Copper vapor laser treatment of granuloma of the vermilion border of the lips arising as a complication after permanent make-up

Background. Granulomas of the vermilion border of the lips (GVBL); as a complication of lip tattooing; inevitably poses cosmetic problems. Surgical excision and cryodestruction are associated with an increased risk of scarring and recurrence of GVBL. Laser therapy can selectively destroy a pigment and achieve the desired cosmetic result with minimal risk of side effects. So laser treatment was reported to be a more relevant method of treatment of GVBL.
 Aim. To evaluate the effectiveness of treatment of GVBL with copper vapor laser (CVL) radiation.
 Case report. 39-year-old female patient; without manifestations of systemic sarcoidosis; reported a 2-year history of granulomas of the lips vermilion border. She had a permanent makeup cosmetic tattoo before the onset of granulomas after lip tattooing. Histopathological examination revealed the presence of pigment in the upper and middle layers of the dermis. GVBL treatment was performed using a CVL during a single procedure; with an average CVL power of 0.60.8 W; with a ratio of 3:2 at wavelengths of 511 nm and 578 nm; exposure time 0.3 s. Light spot diameter 1 mm. CVL treatment led to a pronounced elimination of all GVBL without side effects within five years.
 Discussion. CVL allows a combined mode of exposure; consisting of grinding large granules of pigment to sizes that can be absorbed by the lymphatic system and suppressing VEGF expression using radiation with a wavelength of 578 nm.
 Conclusions. The CVL treatment provided an excellent cosmetic result due to selective photodestruction of the pigment and complete remodeling of the vascular bed associated with GVBL. The high clinical efficiency of eliminating post-tattooing foci of GVBL using CVL without side effects allows us to suggest this method for dermatologists and cosmetologists as a highly effective and inexpensive way to eliminate complications of permanent makeup.

Treatment of the nevus sebaceous of Jadasson by a copper vapor laser

Introduction. Nevus sebaceous of Jadassohn (synonym: nevus of the sebaceous glands) (NSG) presents the congenital malformation of the skin with possible transformation into benign or malignant tumors during the adolescence or adulthood. Commonly appeared on the scalp or neck NSG is frequently concern with cosmetic problems making patients look for opportunities for its removal. Surgical removal of the NSG is related to an elevated risk of scarring. Using ablative lasers has proven to be effective in the removal of small NSG. However, the removal of medium and large NSG with ablative lasers was reported to be linked with a high risk of scarring and recurrence. The removal of the medium-sized NSG with a copper vapor laser (CVL) is described here for the first time.
 Case report and procedure. Laser removal of NSG (linear sized of 27 mm) was performed in a 25-year-old female patient with Fitzpatrick skin type II during eight CVL treatments. Laser settings were selected as follows: the average power of 1 W at the power ratio of 3:2 radiation at a wavelength of 511 and 578 nm. Pulse duration 20 nanoseconds, reprate 16.6 kHz, exposure duration 200 ms, and the light spot's diameter on the skin 1 mm.
 Results. After 8 procedures, the skin in the area of the removed NSG acquired a natural color and appearance. During 24 months of follow-up, there was no hyperpigmentation or signs of scars in the irradiated area. No relapses were observed for 24 months after the CVL removal of NSG.
 Conclusion. The application of non-ablative CVL removal of NSG ensured a desired cosmetic result without side effects.

Metal vapor content of an electric arc initiated by exploding wire in a model N2 circuit breaker: simulation and experiment

A conductive wire can explode by rapidly heating it to vaporization temperature by flowing a current through it. This process is utilized to generate high-temperature high-density plasmas. The temperature and pressure distributions at the time of the explosion are not easily measured. Moreover, the amount of metal vapor from the wire that remains within the arcing area is unknown. This work presents the whole-process model of a single-wire electrical explosion from solid-state to plasma formation. For this purpose, the voltage drop and resistance of the exploding copper wire in solid-state are simulated through a zero-dimensional thermo-electrical model. Then, compressible Euler equations are implemented with nodal discontinuous Lagrange shape functions in a one-dimensional model to compute the flow of the generated copper vapor (due to the wire explosion) in surrounding nitrogen gas. The aim is to calculate the distributions of pressure, density, velocity, temperature, and mass flow along the cylindrical shock waves to estimate the arc’s copper/nitrogen mixture ratio in free burning and nozzle constricted arcs. This mixture ratio is used to calculate the precise percentage of the metal vapor in the arcing area and to calculate Townsend growth coefficients utilizing to estimate the streamer breakdown of the mixture. The simulation results show good agreement with the experimental results in terms of the temporal evolution of the plasma channel boundary, the shock front speed estimation as well as the arc voltage magnitude numerically calculated deploying the extracted mixture percentage from this study, manifesting the validity of the model. It shows that despite the low-pressure studies, the exploding wire method is not suitable for circuit breakers employing supercritical fluids as the insulation.

Exploration of Jitter in Solid-State Switch-Based Pulse Power Supply of Copper Vapor Laser

The copper vapor laser (CVL) is the most powerful and efficient resonance metastable metal-vapor laser having widespread applications. Jitter requirements are very stringent when the CVL is operated in the oscillator–amplifier configuration. Jitter in the laser affects proper synchronization and thereby affects the output power and its stability. Although thyratron-based power supplies have low jitter, it has limited operational life. So, solid-state switch-based pulse power supply is preferable. In the solid-state switch-based pulse power supply of CVL, several parameters simultaneously contribute to jitter in the laser optical output. To observe the parameter-affecting jitter and its contribution, we carry out MATLAB simulations, which are experimentally validated. We demonstrate by simulation and experiments that variations in the laser load impedance significantly contribute to jitter and, by minimizing the effect of laser load variations on the power supply, jitter in the laser can be significantly reduced.

Unified modelling of low-current short-length arcs between copper electrodes

In this work, we present for the first time a unified model of a low-current short-length arc between copper electrodes. The model employs one-dimensional fluid description of the plasma in argon and copper vapour at atmospheric pressure and the heat transfer in the electrodes made of copper. The solution of the particle and energy conservation of electrons and heavy particles is coupled with the solution of the Poisson equation, from which the self-consistent electric field is obtained. The operation of the non-refractory cathode is based on thermo-field emission. Heat fluxes from the plasma to the electrodes are considered so that a phase change and evaporation from the cathode and a release of copper atoms into the plasma are taken into account. The influence of the copper atoms and ions on the plasma properties is analysed and discussed. The model’s predictions are compared with experimental data and a qualitative agreement is obtained besides the restrictions of the one-dimensional fluid model.

LASER SURGERY OF NEVUS OF OTA AND NEVUS OF ITO

Introduction. Clinical variants of congenital melanocytosis in the dermis- nevus of Ota and nevus of Ito (NOI) - may cause marked cosmetic effects; they fail to regress and are reported to be associated with the risk of malignancy. Purpose. To develop criteria and the algorithm for selecting the optimal laser system and radiation specifications to remove NOI considering specific properties of the optical pattern of skin lesions having different locations and melanin concentration. Methods. A scientific and analytical review of publications indexed in PubMed, ScienceDirect, Embase, Web of Science, Russian Medicine, RSCI. Calculation of laser radiation absorption coefficients for various pathomorphological variants of dermal melanocyte locations, given the peculiarities of laser light interaction with targeted photothermophores in NOI focus. Results. The authors present data on epidemiology, history and clinical features of congenital derma melanocytosis of nevus of Ota and nevus of Ito (NOI) - localized, predominantly in periocular and periclavicular regions. Molecular mechanisms of NOI progression in children and adolescents are discussed. There are also data [WU1] on the efficacy and risks of side effects when treating NOI lesions with ruby (wavelength 694 nm), alexandrite ( wavelength 755 nm) and neodymium ( wavelength 1064 nm) laser light. Effectiveness and features of side effects of different wavelengths of laser light are compared. In the article, one can find criteria for selecting an optimal option for NOI laser treatment: maximal efficiency assessed by the visual analogue scale (VAS), number of laser sessions and severity of early and late side effects. For the first time, the authors present data on calculations of quantitative characteristics of optic skin biophotonic pattern if a melanocyte is localized in the papillary and reticular dermis in periocular zone. Conclusion. The obtained calculations on optic characteristics of skin biophotonics suggest [WU2] that two-wave laser irradiation with wavelengths 511 nm and 578 nm will be highly effective with a minimum risk of side effects when removing atypical melanocytes in case of congenital melanocytosis in the papillary and reticular dermis in periocular zone. Algorithms for different pathomorphological variants of melanocyte locatied in the dermis in NOI focus have been proposed to obtain an optimal modality for laser treatment using two-wavelength laser light with 511 nm and 578 nm which is generated by Russian-made copper vapor laser system "Yakhroma-Med" manufactured by Lebedev Physical Institute subordinate to the Russian Academy of Sciences (RAS).

Dependence of phantom current in a metal vapor laser on electrode geometry

It is observed that the discharge current in a copper vapor laser rises prior to the voltage breakdown. This current, which appears almost 50 ns before the discharge breakdown and is equivalent to almost 70% of the peak current at the time of breakdown, is termed the phantom current. It is reported that by reducing the residual electron density (phantom current) in a metal vapor laser (MVL), its performance can be significantly improved. Metallic pins are used in the electrode to facilitate discharge in the long discharge tube. Besides augmenting the discharge during the initial stage, it has a significant impact on the laser performance. In this paper, we find out the correlation between the phantom current and the electrode pin geometry and then present the optimum electrode geometry for improved laser performance. It was observed that the number of pins in the electrode affects the localized electric field in the nearby region and plays a dominant role in the quantum of the phantom current in the discharge tube of the laser. The MVL system was tested with electrodes that had a different number of pins (zero, eight and 36) and it was found that the phantom current is minimum when the electrode has zero pins and highest with an eight-pin electrode.

Kinetic simulations of laser-induced plume expansion from a copper target into a vacuum or argon background gas based on ab initio calculation of Cu–Cu, Ar–Ar, and Ar–Cu interactions

The kinetic simulations of plume expansion induced by pulsed laser heating of a copper target in a vacuum or low-pressure argon background gas are performed based on the direct simulation Monte Carlo (DSMC) method and ab initio quantum mechanical calculation of interactions between copper and argon atoms. The potential energy curves (PECs) for Cu–Cu, Ar–Ar, and Ar–Cu interactions are obtained in density functional theory (DFT) calculations with the van der Waals (vdW) correction. The computed Cu–Cu PEC is strikingly different from the Lennard-Jones (LJ) potentials with semi-empirical parameters, which were previously suggested for kinetic simulations of the copper vapor flows. It is found that the Lorentz–Berthelot rule cannot reliably predict the parameters of the LJ potential for cross-species Ar–Cu interaction. The DFT-vdW PECs are fitted by the Morse long-range (MLR) potentials. The MLR potentials are used to compute the outcomes of binary collisions in the DSMC method based on the solution of the classical scattering problem and to parameterize the variable hard sphere (VHS) collision model. The results of the DSMC simulations based on DFT-vdW PECs are compared with the results obtained based on various parameterizations of the VHS model. It is shown that the previously developed parameterizations of the VHS model can either over- or underestimate the plume temperature and density compared to the results obtained based on the DFT-vdW PECs. The simulations also reveal the strong effect of the cross-species collision model parameters on the flow structure in the mixing layer, which is dominated by molecular diffusion.

Treatment of сongenital melanocytic nevus in infants and children by a dual-wavelengths copper vapor laser

Introduction.Congenital melanocytic nevus (CMN) is detected at birth or shortly after birth in 1% of infants. The localization of CMN in aesthetically significant areas causes a decline in child self-esteem and causes concern for his parents. Surgical excision of skin areas with CMN is associated with an increased risk of cosmetic side effects and is often followed by long-term stress conditions after the invasive intervention.
 Aim of the study.To evaluate the efficacy of the CMN removal in infants, children and adolescents with the dual-wavelengths copper vapor laser (CVL) radiation.
 Patients and Methods.Medium-sized (up to 9 cm) single CMN was treated in nine fair-skinned patients: seven girls and two boys, aged from 2 months to 16 years. The procedures were carried out at an average CVL power of 0.61.0 W, with a power ratio of 3:2 at 511 nm and 578 nm wavelengths, and an exposure time of 0.20.3 s. Light spot diameter 1 mm. The treatment was carried out during 210 sessions with an interval of 12 months between sessions.
 Results.In children and adolescents, the treatment of CMN with CVL dual-wavelengths radiation made it possible to achieve significant clarification of the involved area without hypertrophic scars. The duration of the healing of the irradiated area lasted 23 weeks. Side effects were manifested with subtle skin atrophy.
 Conclusion.The high efficacy of CVL removal of medium-sized CMN in infants and children using the dual-wavelengths CVL radiation without pronounced side effects allows introducing such an approach in the clinical practice of pediatric dermatologists and cosmetologists.

Development of ultrathin thermal ground plane with multiscale micro/nanostructured wicks

In this paper, TGPs with thickness of around 0.53–0.6 mm are developed with copper plate as the casing material, nanostructured copper foam as the wick and electroplated copper pillar as the support of vapor core. The effects of charge amount of water, nanostructured wick, the number of copper foam layers and vapor core thickness on the thermal performance of the developed TGP are experimentally studied. It is found that increasing the number of copper foam layers or vapor core thickness can greatly lower the TGP thermal resistance. Specifically, a TGP with a double layers copper foam wick has a much better thermal performance than that with single layer even though the total wick thickness and porosity remain unchanged. Experimental results also show that the multiscale micro/nanostructured wick is beneficial for improving the TGP thermal performance. Small change of vapor core thickness can lead to great change of TGP thermal performance. The ultrathin TGP can reach an effective thermal conductivity of 2207 W/(m·K) at an input power of 22.66 W over a heating area of 8 mm × 8 mm.

Statistical Model for the Energy Exchange during Copper Vapor Condensation in an Inert Gas Atmosphere

Statistical analysis of the results of molecular dynamics (MD) calculation of gas-phase “self-assembling” of nanoclusters during metal vapor condensation revealed the laws of energy transfer between metallic clusters and inert gas atoms. A model is proposed to determine the parameters of heat exchange between clusters and the environment at the initial stage of condensation. This model is based on averaged MD data on the interaction between small clusters and argon atoms. The parameters that can be used to transfer information from MD to a macroscopic condensation model are numerically determined. The results obtained can be used to describe nucleation to predict a nanoparticle size distribution in the production of metallic powders.

Production and Use of Selenium Nanoparticles as Fertilizers.

The synergy problem was discussed linking Se nanoparticles and different soil fertility agents. Se zero-valent-state nanoparticles were investigated as fertilizers and antioxidants. A technology was proposed for producing Se zero-valent-state nanoparticles. Se nanoparticles were obtained by laser ablation of Se in water using a fiber ytterbium laser, with a wavelength between 1060 and 1070 nm, a pulse repetition rate of 20 kHz, a pulse duration of 80 ns, and an average power of 20 W, and a copper vapor laser with wavelengths of 510.6 and 578.2 nm and an average power of 8 W. The main particle mass part shifted from 800 nm to a size less than 100 nm, corresponding to the increase in the laser fragmentation time. The resulting nanoparticles were monodisperse in size and mass. The Se nanoparticle water suspension was introduced into the soil. The soil Se nanoparticle concentrations were about 1, 5, 10, and 25 μg kg–1. An experiment was carried out in a climate chamber in two series: (1) growing plants in soil imitating the standard organogenesis environment conditions such as illumination of 16 h per day, temperature of 22 °C, soil humidity of 25% SDW, and an experiment duration of 30 days and (2) growing plants in soil under changing environmental conditions of organogenesis. The standard environmental conditions for the first 10 days are illumination of 16 h day–1, temperature of 22 °C, and soil humidity of 25% SDW. The plant stress for 5 days is hyperthermia of 40 °C. The standard environmental conditions for the next 15 days are illumination of 16 h day–1, temperature of 22 °C, and soil humidity of 25% SDW. At standard organogenesis, the plant leaf plate surface area was 30 ± 2 cm2 in the control option, and the Se nanoparticle doses were correspondingly 1 μg kg–1 for 32 ± 3 cm2, 5 μg kg–1 for 37 ± 2 cm2, 10 μg kg–1 for 38 ± 3 cm2, and 25 μg kg–1 for 28 ± 4 cm2. Hyperthermia stressed plant growth was studied. The highest plant growth rate was in Se nanoparticle concentrations of 5 and 10 μg kg–1. The eggplant growth on the soil with the Se nanoparticle addition at a concentration of 10 μg kg–1 of leaf plate surface area was twice compared to the eggplant growth in untreated soil. The same was for tomato plants. The leaf plate surface area of the cucumber plant grown using Se nanoparticles was 50% higher compared to the control option. The Biogeosystem technique methodology of 20–45 cm soil-layer intrasoil milling for soil multilevel aggregate system formation and intrasoil pulse continuous-discrete watering for soil water regime control was proposed for the Se nanoparticles for better function in the real soil, providing a synergy effect of soil mechanical processing, nanoparticles, humic substances, and polymicrobial biofilms on soil fertility.
