Numerical analysis on temperature dependence of XeCl-lasing characteristics

Abstract

The recombination rate constants for Xe++Cl−+Ne→XeCl*+Ne and NeXe+ +Cl−+Ne→XeCl*+2Ne have been calculated in a temperature range of 100–400 K. At 7.34×1019 cm−3 of gas density, both rate constants of the recombinations are found to increase to ∼7.5×10−6 cm3/s at 120 K, a factor of ∼4 higher than that at room temperature. The temperature dependence of XeCl-lasing characteristics has also been simulated by a steady-state kinetic-simulation code. The simulation has indicated not only the enhancement of the laser output, but also the reduction of the halogen concentration in the lower temperature range.
