Abstract
The paper presents the results of numerical simulation of one of the least studied excimer lasers, a KrCl molecule laser. The simulation was carried out in a 1D approximation, where laser radiation were calculated along the optical axis between plane-parallel mirrors, and the system of kinetic equations and the Boltzmann equation were solved in each transverse layer of the active medium. The theoretical data well agree with the results for the EL series KrCl laser (HCEI SB RAS). The effect of the excitation discharge width on the energy characteristics of the laser is numerically shown. The suggested model and the obtained estimates can be used as tools for optimizing initial parameters when developing more powerful laser systems.
