摘要
对传统的稳模式热稳条件进行了推广，使之也可适用于非球面驻波稳定腔的其它谐振腔，如环形腔等；引入了稳模式弱热稳条件的概念，进而提出了一种折衷的优化设计方法———使谐振腔同时满足稳功率热稳条件和稳模式弱热稳条件，从而使得激光器的输出既稳功率又具有一定的模式热稳定性，如发散角的热稳定性；此外，还给出了球面驻波稳定腔、球面环形稳定腔的稳模式强。
Abstract The mode thermo stability conditions for the modes of a conventional linear resonator are developed to apply to a general resonator. The concept of weak thermo stability is introduced, and a new design method,which satisfies both the weak thermo stability conditions for the resonator modes and the thermo stability conditions for the output power, is proposed. With this method, one can make the output power thermo stable and the resonator modes partially thermo stable (for example, the divergence angle can be made thermo stable). Furthermore, analytic solutions to the strong and weak thermo stability conditions for several kinds of resonators are obtained.
