| Abstract: | Measurements of optical emission from the ablation plume of metal Al by XeClexcimer laser are reported.The effects of the surrounding atmosphere pressure(argon,and helium)over the range 13.3Pa to 101.3kPa on optical emission was studied. The results are qualitatively explained using a simple model based on optical emission arising from inelastic collision between the elemental species and electron with high.kinetic energy. |
