Abstract
By numerical simulations was investigated the effect of the mixture of gases in the XeF(C-A) amplifier hybrid laser system THL-100 on the main channels of energy loss. It is shown that an increase in the buffer gas pressure N2 from 100 to 760 Torr leads to an increase in the fraction of absorbed energy transmitted to the upper laser level XeF(C, ν = 0). Increasing the partial pressure of XeF2 causes an increase of energy loss in the process of quenching XeF(B , C) and reduce the energy transferred to the XeF(C, ν = 0) state.
