【摘要】：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2.17kW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。
[Abstract]:The development of the vector polarized beam has put forward new requirements for the mode calculation of the polarization sensitive resonator. Based on the Fox-Li iterative method and the Jones vector theory, a vector Fox-Li iteration method for the polarization sensitive resonator is proposed. This method can calculate the vector partial vibration mode of the polarization sensitive resonant cavity, including the angular polarization TE01* mode and the radial bias. The mode of vibration TM01* is calculated by Matlab programming. The calculation results are in agreement with the theory, and the correctness of the method is proved. Then, based on the axis fast flow (FAF) CO2 laser platform, the combined axis cone mirror is used as the tail mirror of the resonant cavity, and the output of the angular polarization mode of 2.17kW is obtained. The simulation results of the vector Fox-Li iterative method coincide. The experiment proves the validity and accuracy of the method. The vector Fox-Li iteration method is of great guiding significance for the analysis and design of the polarization sensitive resonator.
