Abstract
This paper introduces the simulation of the thermal focal length brought by the Conduction Cooling End-Pumped Slat(CCEPS) laser amplification module under the action of thermal stress. Through simulation analysis, it is found that the thermal focal length of CCEPS lath crystal is affected by two factors, temperature distribution and stress distribution. One of these two factors brings a positive lens effect, the other may bring a negative lens effect, and it may also bring a positive lens effect at the same time. In order to find out the law of thermal lens effect in CCEPS module, a comprehensive simulation analysis of CCEPS module is carried out. This paper provides a strong theoretical support for further experimental verification.
