摘要
针对侧面泵浦的固体激光器工作介质产生的热透镜效应进行了分析 ,建立热传导方程。采用有限元分析的方法对不同泵浦条件下激光棒内的温度场和应力变化进行分析。提出补偿热透镜效应的有效措施。
The thermal-lens effects of side-pumped solid-state lasers are studied and heat exchange equation is established.The temperature and thermal stress of laser medium in different pumping condition are analyzed by finite element method.Some compensation on thermal-lens effects is discussed.Thermal focal distance in different compensation condition is compared through experiment.
