矢量偏振光束的发展对偏振敏感谐振腔的模式计算提出了新的要求,基于Fox-Li迭代法和琼斯矢量理论,提出了用于偏振敏感谐振腔的矢量Fox-Li迭代法。该方法可以计算偏振敏感谐振腔内的矢量偏振模式,包括角向偏振TE01*模和径向偏振TM01*模。通过Matlab编程对球面偏振敏感谐振腔内的矢量偏振模式进行数值计算,计算结果与理论一致,证明了该方法的正确性。然后基于轴快流(FAF)CO2激光器平台,采用组合轴锥镜作为谐振腔的尾镜,得到了2.17 kW的角向偏振模式输出,与矢量Fox-Li迭代法仿真结果吻合,实验证明了该方法的有效性和准确性。矢量Fox-Li迭代法对于偏振敏感谐振腔的分析和设计具有重要的指导意义。
