Abstract
this article a spectroscopic research on laser-produced Tin and Zinc plasmas using the optical emission spectroscopy (OES) technique. Plasmas can be produced from a solid tin and zinc targets irradiated with a pulsed laser in room environments. The spectrum is recorded for the Sn, Zn laser plasma Nd: YAG with a wavelength of (1064) nm, a duration of (9) ns, and a frequency of (6) Hz and a focal length of (10) cm within the energy range (300-800)mj. By using the ratio line strength formula, the electron temperature (Te) can be calculated and the result is for Zinc (Zn) plasma (2.11 ev) and tin (Sn) plasma (1,227 ev). The Saha-Boltzmann equation will be used to calculate electron density (ne) in this method and the values for zinc (Zn) (3.3 cm-3)and tin (Sn) (2.1 cm-3). The plasma parameters, such as plasma (fp), Debye duration (λD), and Debye number (ND), were calculated in the proposed document.
