摘要
根据谐振腔理论，详细分析了内含热透镜的平凹腔的动态稳定性。指出在某一特定情形下，平凹腔可以只存在单一的稳定区。在此基础上，笔者以最佳输出功率曲线为目标，选择了一组腔参数，实验结果表明，该激光器在较宽的泵浦功率范围内，其输出功率与输入呈现良好的线性关系。
Based on cavity theory,the characteristics of dynamic stability zone of a parallel concave laser cavity are analyzed in detail,taking account of thermal lens effect equivalent to convex lens.In gene ral ,the laser with parallel concave cavity can operate in one of two dynamic stability zones.We found that,in a special case,the parallel concave cavity has only one dynamic stability zone.According to theoretical analysis,we selected a set of cavity parameters and carried out the experiments,taking Nd∶YAG as a exmple.The results show that the output power of laser increase with the pumping power in a rather wide range.
