Technical Problem
[0004]但由于大部分泵浦功率通过无辐射跃迁和量子亏损转化为热能，增益介质的工作温度大幅升高，产生的热效应对简并腔激光器输出产生明显的影响，如激光器的阈值升高、热透镜效应、热应力双折射和退偏效应，情况严重时使激光器停止运转
Benefits of technology
[0014]本实用新型的技术方案至少具有如下优点和有益效果：本发明综合考虑各元件之间的光学特性，如激光晶体本身的厚透镜效应，光学元件的衍射孔径限制，明确给出了光学元件之间的相对位置关系和距离的解析形式，实现完美简并腔激光器的构建，且结合变焦透镜的动态变焦特性，通过压控焦距实现在不同功率下的动态简并腔激光器的构建，实现了降低增益介质的热透镜效应的效果，减少了功率变化对腔体简并性的影响。
