角状螺旋固体激光器偏振特性的理论分析

Theoretical Analysis of Properties of Polarization in Eckige-Schraube-Laser

利用琼斯矢量和琼斯矩阵的形式对ＥＳ激光器的偏振特性作了分析，得到光线在激光腔内往返一周的琼斯变换矩阵．证明了ＥＳ激光器具有偏振态自再现性质，同时研究了偏振损耗的变化规律．给出了计算结果。

The properties of Polarization of ES-Laser are analysed through Jones vectors andJones matrixes. The Jones transformation matrix representing a round trip of the ray in thelaser cavity has been obtained. The properties of self-reproduction of polarization mode havebeen achieved. The variation regulation of polarization loss with the incidence angle to theend face of the laser medium is discussed, and the calculation results are presented.
