摘　　要：研究了重复率高功率强激光作用下热平衡状态激光的热透镜效应。观察和分析了激光棒从非热平衡到热平衡状态的热透镜效应,通过采取插入光学补偿系统的方法,使得激光器系统在热平衡状态下的热透镜效应得以消除,从而得到较好的激光输出和稳定的实验系统。The thermal lens effect of thermal balance laser under high powerful and repetitive laser was researched. The thermal lens effects of laser rods from nonthermal balance to thermal balance were observed and analyzed. We inserted the optical compensators in optical paths,and the thermal lens effect was eliminated in thermal balance. So we got a good laser output. And this work provides a means to study the thermal lens effects of laser medium and design high powerful and repetitive lasers.
