Abstract

The results of computer simulation by the finite element method of thermoelastic stresses arising during pulsed pumping in ZnSe:Fe disk laser crystals with a different doping profile are presented. The thresholds for the occurrence of parasitic generation in a disk ZnSe:Fe laser are numerically analyzed at these doping profiles. Based on the maximum output pulse energy in a ZnSe:Fe laser and the maximum distortion of the optical density of the active element, different doping profiles were compared.
