管状固体激光器中的热致退偏分析

Analysis of thermal depolarization in a tube solid-state laser

对非均匀发热的管状YAG激光器的热应力双折射和热致退偏进行了深入研究,计算模拟了不同管壁厚度和泵浦功率下的热致双折射光程差和热致退偏损耗。

Based on the inhomogeneous heat distribution,the thermal birefringence and thermal depolarization have been studied in a tube YAG laser.The optical length differences of thermal birefringence and the losses of thermal depolarization have been calculated under different thicknesses of the laser tube and different pump powers.
