摘要

A spectroscopic study on laser-produced tin plasma utilizing the optical emission spectroscopy (OES) technique is presented.Plasma is produced from a solid tin target irradiated with pulsed laser in room environment.Electron temperature is determined at different laser peak powers from the ratio of line intensities,while electron density is deduced from Saha-Boltzmann equation.A limited number of suitable tin lines are detected,and the effect of the laser peak power on the intensity of emission lines is discussed.Electron temperatures are measured in the range of 0.36 eV-0.44 eV with electron densities of the order 1017 cm-3 as the laser peak power is varied from 11 MW to 22 MW.
