摘　　要：将PMMA，PC，COP等具有折射率负温度系数特性的固体光学元件插入Nd：YAG固体激光器的激光介质中，可以有效补偿激光介质工作产生的热透镜效应，优化光束质量，并且这种方法是一种动态补偿，不受泵浦功率变化的影响。A solid optical element of negative temperature coefficient of refractive index, such as PMMA, PC, COP is used to insert between the laser materials of Nd：YAG solid laser to compensate the thermal lens effect. Remarkable compensating effect and good output beam quality is achieved by the method, which is a dynamic compensation independent of the pumping power level.

关 键 词：ND:YAG固体激光器 热透镜效应 折射率负温度系数 动态补偿
