Estimation of the thermal state and the destruction limits of the Cr:LiSAF laser active medium

Abstract

The article includes estimation of thermal operating conditions of laser with an Cr:LiSAF active medium. The results of thermal state simulation depending on the pump intensity are presented. The stress-strain state of active medium is determined with taking into account the thermal calculation and crystal anisotropy. Destruction criteria are considered with taking into account the crystal grid defects.
