Optical properties of Dy3+-doped CaYAlO4 crystal

Optical spectroscopic properties of Dy3+ ions in Dy:CaYAlO4 single crystals were investigated, aiming at evaluating the potential for visible laser applications. The crystals were grown by the Czochralski technique in reducing atmosphere in order to circumvent the color-center formation in this host material. Chemical compositions of the as-grown crystals were determined by electron probe micro-analysis. Absorption and emission spectra were recorded in the visible and near infrared spectral range at room temperature. Experimental oscillator strengths derived from the ground-state absorption transitions were used to fit the electrostatic, spin-orbit coupling as well as Judd-Ofelt intensity parameters. The theoretical electric dipole as well as magnetic dipole oscillator strengths, fluorescence branching ratios, and radiative lifetime were calculated in the framework of Judd-Ofelt theory. Experimental and calculated results showed that the yellow 4F9/2→6H13/2 transition features the largest branching ratio and emission cross-sections under 453-nm excitation. Fluorescence decay profiles were recorded to analyze the fluorescence lifetime of the 4F9/2 level. Anisotropy of magnetic-dipole transitions was observed in the spectroscopic study and discussed in detail.

Fluorescence branching ratios and magnetic tuning of the visible spectrum of SrOH

The magnetic tuning of the low rotational levels in the X̃2Σ+ (0,0,0), Ã2Πr (0,0,0), and B̃2Σ+ (0,0,0) electronic states of strontium hydroxide, SrOH, have been experimentally investigated using high resolution optical field-free and Zeeman spectroscopy of a cold molecular beam sample. The observed Zeeman shifts and splittings are successfully modeled using a traditional effective Hamiltonian approach to account for the interaction between the Ã2Πr and B̃2Σ+ states. The determined magnetic g-factors for the X̃2Σ+, Ã2Πr, and B̃2Σ+ states are compared to those predicted by perturbation theory. The dispersed fluorescence resulting from laser excitation of rotationally resolved branch features of the 000B̃2Σ+←X̃2Σ+, 000Ã2Π3/2←X̃2Σ+ and 000Ã2Π1/2←X̃2Σ+ transitions have been recorded and analyzed. The measured fluorescence branching ratios are compared with Franck-Condon calculations. The required bending motion wave functions are derived using a discrete variable representation (DVR) method. Implications for laser slowing and magneto-optical trapping experiments for SrOH are described.

Czochralski growth and spectral investigations of Er:GSAG laser crystal

Er3+ doped GSAG laser crystal with high optical quality was grown successfully by the Czochralski method for the first time. The structural parameters and the high crystalline quality of this crystal were determined. Judd-ofelt (J-O) parameterization scheme was applied to analyze the absorption spectra at room temperature. Accordingly, the lines strengths, oscillator strengths, transition probabilities, fluorescence branching ratios, and radiative lifetimes were calculated to characterize the laser properties of Er:GSAG crystal. Additionally, the fluorescence spectra and lifetimes of Er:GSAG crystal were measured and studied. The stimulated emission cross-section spectra and gain cross-section spectra were evaluated for 4I13/2 →4I15/2 (1.5–1.6 µm) transitions which indicate high potential of 1 at% Er:GSAG for laser emissions at 1567 and 1605 nm. Furthermore, the possibility of Er:GSAG crystal to realize the visible laser output pumped by the GaN LDs were initially studied and analyzed.

Temperature sensing, excitation power dependent fluorescence branching ratios, and photothermal conversion in NaYF_4:Er^3+/Yb^3+ @NaYF_4:Tm^3+/Yb^3+core-shell particles

Temperature controllable photothermal therapy (PTT) requires a nanoplatform in which the optical temperature sensor and photothermal calorifier are integrated together. To establish such a nanoplatform, in this work we designed a NaYF4:Er3+/Yb3+@NaYF4:Tm3+/Yb3+ core-shell structure, and studied on its temperature sensing and photothermal conversion. The core-shell nanoparticles were prepared via a thermal decomposition method; furthermore, their crystal structure and microscopic morphology were characterized by means of XRD and SEM/TEM. The properties of temperature sensing and excitation power dependent fluorescence branching ratios were investigated. It was found that the temperature sensing could be achieved based on the fluorescence intensity ratio of green emissions from Er3+, but could not be realized by using other fluorescence intensity ratios. The photothermal conversion was demonstrated under 808 and 980 nm co-excitation, and the dependences of photothermal conversion on the excitation power and irradiation time of 808 nm laser were observed. Moreover, it was also found that the core-shell particles could effectively accelerate the evaporation of anhydrous ethanol, thus implying the photothermal conversion under single 980 nm laser excitation could also be achieved.

Enhanced 1.80 μm fluorescence in Er3+/Yb3+/Tm3+ tri-doped tellurite glass for fiber lasers

Improving the lasing emission property of rare-earth doped vitreous material is a research topic. In this paper, Er3+/Yb3+/Tm3+ tri-doped tellurite glasses with and without WO3 component were synthesized using melt-quenching technique and the effect of WO3 addition on the 1.80 μm band fluorescence of Tm3+ was investigated. The obtained samples were characterized by X-ray diffraction (XRD) pattern, differential scanning calorimeter (DSC) curve, Raman spectrum, UV/Vis/NIR absorption spectrum, near-infrared emission spectrum and fluorescence decay curve. The XRD pattern confirmed amorphous structural nature of synthesized tellurite glass, the DSC curve revealed good thermal stability with ΔT>100 °C and the Raman spectrum displayed a stretching vibration band around 920 cm−1 for glass host with WO3. Under the excitation of 980 nm laser diode (LD), the intense 1.80 μm band fluorescence of Tm3+ originated from the 3F4→3H6 transition was observed in the Er3+/Yb3+/Tm3+ tri-doped tellurite glass and the intensity increases further with the addition of a certain amount of WO3, which is attributed to the enhanced energy transfers from Yb3+ (Er3+) to Tm3+ ions due to the increased phonon energy of glass host. The energy transfer mechanism between them was elucidated by analyzing fluorescence decay behavior of Tm3+ and quantitatively calculating energy transfer coefficient as well as phonon contribution ratio. Meanwhile, based on the absorption spectrum, some important spectroscopic parameters such as Judd-Ofelt parameter, spontaneous radiative transition probability, fluorescence branching ratio, absorption and emission cross-sections, and gain coefficient spectrum were calculated to reveal spectroscopic properties of doped Tm3+ ions. The obtained results indicate that Er3+/Yb3+/Tm3+ tri-doped tellurite glass with an appropriate amount of WO3 is a promising gain medium applied for the 1.80 μm band solid-state lasers.

Optical spectroscopy of holmium doped K2LaCl5

Spectroscopic results on the infrared emission properties of trivalent holmium (Ho3+) doped potassium lanthanum chloride (K2LaCl5) are presented. Using ~900nm excitation, Ho3+ doped K2LaCl5, which has a maximum phonon energy of 235cm−1, exhibited the infrared emissions at ~1660, ~1995, and ~3900nm at room temperature. The mid-infrared emission at 3900nm originated from the 5I5 → 5I6 transition of Ho3+ ions with an exponential decay time of ~7.8ms at room temperature. The fluorescence lifetimes were almost independent of temperature, indicating a negligibly small non-radiative decay rate for the 5I5 excited state, as predicted by the energy gap law for low phonon energy hosts. The Stark level energies of the lower 5IJ manifolds in Ho:K2LaCl5 were resolved from spectroscopic results performed at cryogenic temperatures. The transition line-strengths, radiative lifetimes, and fluorescence branching ratios were investigated by using the Judd-Ofelt method. In addition, the peak emission cross-section of the 5I5 → 5I6 transition was calculated to be 1.8 × 10–20cm2 at ~3890nm.

Crystal growth and spectroscopic analysis of Tm, Ho singly-doped and Tm/Ho co-doped CaLaGa3O7 NIR laser crystals

Growth of Tm, Ho singly-doped and Tm/Ho co-doped CaLaGa3O7 crystals by Czochralski method are investigated for the first time. The polarized absorption spectra, fluorescence spectra and luminescence decay curves of Tm: CaLaGa3O7, Ho: CaLaGa3O7 and Tm/Ho: CaLaGa3O7 crystals are reported. Based on the Judd–Ofelt theory and the polarized absorption spectra, the spontaneous transition probabilities, the fluorescent branching ratios and the radiative lifetimes were calculated. The crystals exhibit a broad emission band at about 2.0 μm, corresponding to 3F4→3H6 of Tm3+ and 5I7→5I8 of Ho3+, respectively. The energy transfer parameters in Tm/Ho: CaLaGa3O7 crystal between Tm3+ and Ho3+ are theoretically analyzed. These results show that Tm: CaLaGa3O7, Ho: CaLaGa3O7 and Tm/Ho: CaLaGa3O7 crystals are excellent potential tunable laser media for the ∼2.0 μm regions.

Around 2 μm fluorescence and energy transfer in Tm3 +/Ho3 + co-doped tellurite glass

In this work, the near-infrared photoluminescence properties in Tm3+/Ho3+ co-doped tellurite glass was investigated. The tellurite glass with composition TeO2-ZnO-Na2O-La2O3 was synthesized using conventional melt-quenching technique and characterized by UV/Vis/NIR absorption and near-infrared emission spectroscopies, fluorescence decay measurement and differential scanning calorimeter (DSC) analysis. Under the excitation of 808nm laser diode (LD), a broadband 2.0μm band luminescence ranging from 1600 to 2200nm with a full width at half maximum (FWHM) of 362nm was observed, which was contributed by 1.85μm fluorescence from Tm3+: 3F4→3H6 and 2.05μm fluorescence from Ho3+: 5I7→5I8. The fluorescence emission of Ho3+ was originated from the energy transfer from Tm3+ to Ho3+ ions, and the energy transfer mechanism was elucidated by analyzing fluorescence decay behavior of Tm3+ and quantitative calculation of phonon contribution joined in the energy transfer process. Meanwhile, based on the absorption spectrum, some important spectroscopic parameters such as Judd-Ofelt intensity parameter, spontaneous radiative transition probability, fluorescence branching ratio, absorption and emission cross-sections, and gain coefficient spectrum were calculated to reveal the spectroscopic properties of doped tellurite glass. Furthermore, from the DSC curve it can be derived that the investigated glass possesses a good thermal stability with ΔT(=Tx−Tg) larger than 152°C. These results indicate that Tm3+/Ho3+ co-doped tellurite glass could be a promising gain medium applied for 2.0μm near-infrared band broad fiber amplifiers and tunable fiber lasers.

Broadband ∼3 μm mid-infrared emission in Dy3+/Yb3+ co-doped germanate glasses

The Dy3+/Yb3+ co-doped germanate glasses with good thermal stability have been prepared by the conventional melt quenching method. The J-O intensity parameters and radiative properties such as spontaneous transition probilities (Arad), fluorescence branching ratios (β) and radiative lifetimes (τrad) were investigated according to the absorption spectrum based on Judd-Ofelt theory. An intense emission around ∼3 μm with the FWHM reaching to 322 nm was obtained in present glasses excited by 980 nm LD. The high spontaneous transition probability (63.94 s−1), large emission cross section (6.0 × 10−21 cm2) and superior gain performance corresponding to the Dy3+: 6H13/2 → 6H15/2 transition were obtained. Moreover, the energy transfer mechanism was analyzed qualitatively, and it was found that the energy transfer from Yb3+: 2F5/2 to Dy3+: 6H5/2 level could be quite efficient. Hence, the results indicated that the prepared Dy3+/Yb3+ co-doped germanate glass could be a potential candidate for ∼3 μm mid-infrared solid state lasers.

Enhanced 573 nm yellow emissions of Dy^3+ via Tb^3+ deactivation in Na_2Gd_4(MoO_4)_7 crystal

A Dy3+/Tb3+ co-doped Na2Gd4(MoO4)7 yellow laser crystal was successfully grown and analyzed. The use of Tb3+ codoping for enhancing the Dy3+:4F9/2→6H13/2 yellow emissions was investigated in the Na2Gd4(MoO4)7 crystal for the first time. In comparison to Dy3+ single-doped Na2Gd4(MoO4)7 crystal, the Dy3+/Tb3+ co-doped Na2Gd4(MoO4)7 crystal possessed a higher fluorescence branching ratio (80.2%), transition probability (3704 s−1), and fluorescence emission cross section (1.34×10−20 cm2) corresponding to the laser transition 4F9/2→6H13/2 of Dy3+. It was found that the introduced Tb3+ enhanced the 573 nm emission by depopulating the population of the laser lower level Dy3+: 6H13/2, and has little influence on the laser upper level Dy3+: 4F9/2 at the same time. These results suggest that Dy3+/Tb3+ co-doped Na2Gd4(MoO4)7 crystal may be an attractive host for developing solid state lasers at around 573 nm under a conventional 450 nm LD.

Judd-Ofelt and laser parameters of Eu3+ ions doped in network restricted matrices

Eu3+ ions were successfully doped in two restricted matrices; Silica sol-gel matrix and silica-ethylene glycol (EG) hybrid matrix (modified sol-gel matrix) with different concentrations to produce transparent silica xerogel Eu samples having no cracking and to select the optimum concentration which then doped with different concentrations of ZnO (as sensitizer) via modified sol-gel method to produce Eu composite zinc oxide. The concentration 2.5wt% was detected as optimum concentration of Eu3+and 0.625% wt for ZnO in modified sol-gel matrix. The compositional dependences of Judd–Ofelt and laser parameters of Eu3+ ions in studied matrices were evaluated and discussed. The FTIR spectrum of the prepared restricted samples was recorded and all structural changes in the samples prepared have been studied. The experimental dipole strengths were calculated from the areas under the absorption bands. The evaluated Judd-Ofelt parameters (Ωλ), using the observed spectral intensities, have been used to calculate various laser parameters viz., spontaneous emission probability (A), radiative life time (τ), fluorescence branching ratio (β) and stimulated emission cross section (σp). The effects of EG and ZnO on optical and lasing parameters of the samples were also discussed.

Spectral investigations on Eu3+ ,Sm3+ -doped and Sm3+ /Eu3+ co-doped potassium-fluoro-phosphate glass emitting intense orange-red for lighting applications.

Potassium fluoro-phosphate (KFP) glass singly doped with different concentrations of europium (Eu3+ ) or samarium (Sm3+ ) or co-doped (Sm3+ /Eu3+ ) was prepared, and their luminescence spectra were investigated. The phase composition of the product was verified by X-ray diffraction analysis. Optical transition properties of Eu3+ in the studied potassium phosphate glass were evaluated in the framework of the Judd-Ofelt theory. The radiative transition rates (AR ), fluorescence branching ratios (β), stimulated emission cross-sections (σe ) and lifetimes (τexp ) for certain transitions or levels were evaluated. Red emission of Eu3+ was exhibited mainly by the 5 D0 →7 F2 transition located at 612 nm. Concentration quenching and energy transfer were observed from fluorescence spectra and decay curves, respectively. It was found that the lifetimes of the 5 D0 level increased with increase in concentration and then decreased. By co-doping with Sm3+ , energy transfer from Sm3+ to Eu3+ occurred and contributed to the enhancement in emission intensity. Intense orange-red light emission was obtained upon sensitizing with Sm3+ in KFP glass. This approach shows significant promise for use in reddish-orange lighting applications. The optimized properties of the Sm3+ /Eu3+ co-doped potassium phosphate glass might be promising for optical materials.

Coupling between surface plasmon resonance and Sm3+ ions induced enhancement of luminescence properties in fluoro-tellurite glasses

Fluoro-tellurite glasses co-activated with Samarium (Sm3+) ions and silver nanoparticles (Ag NPs) were prepared using melt quenching technique. The nucleation and growth of Ag NPs were controlled by thermal annealing process. X-ray diffraction (XRD), transmission electron microscopy (TEM), differential scanning calorimetry (DSC), UV–vis–NIR absorption spectroscopy, photoluminescence (PL) and PL lifetime spectroscopy were used to examine the annealing time dependence of the structural and luminescent properties. The amorphous nature of glasses has been confirmed by XRD spectra. The transmission electron microscopy images show the presence of silver NPs having an average diameter in the range of 20–40nm. Selected area electron diffraction pattern (SAED), as well as EDX analysis spectrum confirm the presence of Ag NPs. Based on the absorption results, the intensity parameters Ωt (t=2, 4, 6), the radiative transition probability (AT), fluorescence branching ratio (βJJ’) and radiative lifetimes (τr) of Sm3+ ions were calculated using Judd-Ofelt theory. The results suggest that Sm3+ ions have been incorporated into Ag NPs, which intensified the electromagnetic field around Sm3+ ions. The luminescence properties of Sm3+ doped glasses were investigated. It was found that the presence of silver NPs nucleated and growth during the annealing process, improves the photoluminescence (PL) intensity and the PL lifetime relative to the transition from the 4G5/2 state to 6H5/2, 6H7/2, 6H9/2 and 6H11/2 states. Maximum enhancement is observed for the sample heat treated for 8h. Such enhancement is mainly attributed to the local electric field created by the SPR of Ag NPs. whereas; the quenching is due to the energy transfer from Sm3+ ions to the silver nanoparticles as well as to the non-plasmonic, molecule likes Ag-particles (ML-Ag). The present results indicate that the glass heat-treated for 8h has good prospect for Laser emissions at 600nm.

A theoretical analysis upon the four-dimensional (4D) spatio-temporal temperature dependent dynamics of 888 nm pumped Nd:YVO 4 dual-rod laser is established, which is valid in both continuous-wave (CW) and acousto-optic (AO) Q-switched pulse lasers conditions. Our model can accurately solve the 4D thermal generation and temperature evolution not only in the steady Q-switched state, but also in the first few unstable giant or dwarf pulses region. Factors including ground state depletion (GSD), energy transfer upconversion (ETU), fluorescence branching ratios, temperature-dependent cross sections and nonradiative relaxations processes are comprehensively considered for precisely estimating thermal effects, valid in both the steady pulse region and the unstable region at the beginning. Moreover, temporal and spatial temperature profiles and their coupling effect on output properties at different repetition-rates are discussed. Experiments of high-power high-repetition-rate 888 nm end-pumped Nd:YVO 4 dual-rod CW and AO Q-switched lasers are also firstly presented and the experimental results enjoy good consistency with our theory.

The main fluorescence band around 646nm is related to the 4G5/2→6H9/2 transition, which has a branching ratio of 45.4% and peak emission cross sections of 1.73×10–21 and 3.13×10–21cm2 for π and σ polarizations, respectively. The results indicate that the Sm3+:NaGd(MoO4)2 crystal may be a potential gain medium of red visible laser pumped directly by commercially available 405nm laser diode.

Effects of Zr^4+ co-doping on the spectroscopic properties and yellow light emissions of Dy^3+ in LiNbO_3 single crystals

A series of zirconium and dysprosium doped congruent LiNbO3 (Zr:Dy:CLN) single crystals with a fixed concentration of Dy3+(1mol%) and varied concentrations of optical damage resistant ion Zr4+ (0, 1, 2, 3mol%) have been grown successfully by the Czochralski technique. The influence of Zr4+ doping on structure and the spectroscopic characteristics of Dy3+ in Zr:Dy:CLN crystals have been investigated. Detailed Judd-Ofelt theory analysis was carried out to determine the Judd-Ofelt intensity parameters and main spectroscopic characteristics, which coincided well with the measured fluorescence performance. The defects, resulting from Li-deficiency or exceeding Zr4+-doping, showed positive influences on the absorbing hypersensitive transition 6H15/2→6F11/2 + 6F9/2 and the parameter Ω2. The stimulated emission cross sections of transition 4F9/2 → 6H13/2 with different Zr4+ concentration were evaluated. Exceeding Zr4+ doping was demonstrated effective for significantly eliminating the negative impact of threshold concentration on emission cross sections. The results showed a negative correlation between yellow fluorescence branching ratio of transition 4F9/2 → 6H13/2 and the symmetry of crystal field. Besides, we proposed the Zr:Dy:CLN single crystals as a candidate material for yellow laser operation.

Tm3+/Yb3+ co-doped tellurite glass with silver nanoparticles for 1.85 μm band laser material

Tm3+/Yb3+ co-doped tellurite glasses with different silver nanoparticles (Ag NPs) concentrations were prepared using the conventional melt-quenching technique and characterized by the UV/Vis/NIR absorption spectra, 1.85 μm band fluorescence emission spectra, transmission electron microscopy (TEM) images, differential scanning calorimeter (DSC) curves and X-ray diffraction (XRD) patterns to investigate the effects of Ag NPs on the 1.85 μm band spectroscopic properties of Tm3+ ions, thermal stability and structural nature of glass hosts. Under the excitation of 980 nm laser diode (LD), the 1.85 μm band fluorescence emission of Tm3+ ions enhances significantly in the presence of Ag NPs with average diameter of ∼8 nm and local surface Plasmon resonance (LSPR) band of ∼590 nm, which is mainly attributed to the increased local electric field induced by Ag NPs at the proximity of doped rare-earth ions on the basis of energy transfer from Yb3+ to Tm3+ ions. An improvement by about 110% of fluorescence intensity is observed in the Tm3+/Yb3+ co-doped tellurite glass containing 0.5 mol% amount of AgNO3 while the prepared glass samples possess good thermal stability and amorphous structural nature. Meanwhile, the Judd-Ofelt intensity parameters Ωt (t = 2,4,6), spontaneous radiative transition probabilities, fluorescence branching ratios and radiative lifetimes of relevant excited levels of Tm3+ ions were determined based on the Judd-Ofelt theory to reveal the enhanced effects of Ag NPs on the 1.85 μm band spectroscopic properties, and the energy transfer micro-parameters and phonon contribution ratios were calculated based on the non-resonant energy transfer theory to elucidate the energy transfer mechanism between Yb3+ and Tm3+ ions. The present results indicate that the prepared Tm3+/Yb3+ co-doped tellurite glass with an appropriate amount of Ag NPs is a promising lasing media applied for 1.85 μm band solid-state lasers and amplifiers.

Samarium doped sodium bismuth silicate glass was synthesized using the melt quenching method. Detailed optical spectroscopic studies of the glassy material were carried out in the UV–Vis-NIR spectral range. Using the optical absorption spectra Judd-Ofelt (JO) parameters are derived.

The principal fluorescence transitions are identified by recording the fluorescence spectrum. Our analysis revealed that the novel glassy system has the optimum values for the key parameters viz. spectroscopic quality factor, optical gain, stimulated emission cross section and quantum efficiency, which are required for a high performance optical amplifier. Calculated chromaticity co-ordinates (0.61, 0.38) also confirm its application potential in display devices.
