角锥棱镜的偏振特性会产生退偏效应影响免调试固体激光器的输出质量和效率, 也可以实现相干互注入用于激光合成领域。无论是光的合成还是退偏效应的消除, 都需要有精确的偏振特性数据。利用解析几何和光线追迹法从理论上推导出角锥六种光回路的Mueller偏振变换矩阵。为了提高测量精度和稳定性, 设计了一种动态检测Stokes参量的方法, 通过实验获得角锥棱镜六种传输光路的高精度数据, 实验与理论的误差率为4.470%, 误差在合理范围内, 可以确定其偏振特性。所做研究将有助于消除角锥棱镜的退偏效应, 提高免调试固体激光器等设备的性能, 提高激光合成效率和质量。

The cube corner reflectors (CCR) have the depolarization effect, which will affect the efficiency of the adjust-free solid state laser, and can also be applied to the beam combination. Both of them require accurate polarization characteristics. The Mueller matrices of 6 transmission light paths of the cube corner were deduced by using analytic geometry and ray tracing. To improve the experiment, a scheme of dynamic detection of Stokes parameter was designed to get high precision data. The error rate is 4.470% and is within a reasonable range. This study have meaning for eliminating the depolarization effect of cube corner, improving the performance of laser and improving the efficiency of beam combination.
