摘要
本文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 ,以屈光度划分了稳区及非稳区 ,并根据稳区分布的对称性及稳腔和非稳腔的性质 ,分析了腔的损耗随泵浦功率的变化关系 ,进而对连续平行平凹腔的Nd :YAG激光器的输出功率特性作了详细分析。实验观测到了输出功率曲线的双峰结构 ,且测得的实验结果与我们的理论分析相一致。
This paper analyzes the performance of plan concave resonators with internal thermal lenses,and gives out stability and unstability regions in terms of dioptric power.Based on the stability region's sysmetry and stable and unstable resonators' characteristics,relationship between resonators' loss and pump power is obtained,and then,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.
