摘　　要：书文综述了透镜谐振腔的解析。介绍了一种热不敏感谐振腔理论,给出其精确解法和设计方法。分析了腔参数变化的影响,得到一些重要结论,用本方法设计了单模Nd:YAG激光器。实验发现了两个不同阈值的热稳工作区;获得单模25W的输出功率;并得到与理论相一致的结果。A theory for laser resonators with low sensitivity to thermal effect was introduced in this paper, the new analytic solution was obtained. The influence of the changing of the cavity parameters was analyzed and some important results were achieved. A monomode Nd: YAG laser was designed by our procedure and our theory was tested and verified through experiments。From the experiments, we found that the laser can operate at two different stable zones which have unequal threshold, and also found that for a reasonably designed resonator, its operating state with stability to thermal effect correspond to the optimum. TEM(?)mode output.
