Modeling of lasing possibility in XeF(C-A) amplifier of the THL-100 laser system

Abstract

Results of experimental measurements and numerical simulations of the N₂ and XeF₂ gas pressure effects on the gain characteristics are presented in the paper. It is experimentally and theoretically is shown that maximum total gain (5-6)×10⁴ achieved at a pump energy E = 240 J, 0.2 Torr XeF₂ and 0.5 atm N₂pressure. Increasing and decreasing of N₂ pressure leads to decrease of the gain. The possibility of the XeF(C-A) amplifier operation in a generator mode is discussed and the theoretical study results of generation are presented. It is shown that an annular laser radiation with energy up to 8.5 J can be obtained. The study results of the influence on the laser energy of N₂ and XeF₂ pressure and reflectance coefficient of output mirror are presented.
