内含热透镜谐振腔的动态工作特性

Dynamic Characteristis of Resonators with an Internal Thermal Lens

分析了内含热透镜平行平凹谐振腔的性质在运行中的变化，按屈光度划分了稳区及非稳区，并根据稳腔和非稳腔的性质，详细分析了连续平行平凹腔Ｎｄ ：ＹＡＧ 激光器的输出功率特性。实验中观测到了输出功率曲线的双峰结构。

Analyzes the performane of plane concave resonators with internal thermal lenses and gives out stability and unstability regions in terms of dioptric. Based on the stable and unstable resonators′ characteristics,a detailed analysis for output power of cw plane concave Nd:YAG laser is presented. Experimental results clearly show the existence of two peak structure which is predicted by theoretical analysis.
