钛宝石激光放大器的激光晶体由高功率激光泵浦,放大脉冲会受到热透镜、高阶像差,及热畸变的影响,其中的热效应不可忽略,因此必须进行有效的冷却。分析、解决热透镜效应的基础
The laser crystal of the Ti: Sapphire laser amplifier is pumped by a high-power laser. The amplified pulse is affected by the thermal lens, higher-order aberrations, and thermal distortion. The thermal effects are not negligible and must be effectively cooled. Analyze and solve the basics of thermal lensing
