摘要

我们研究了Nd:YAG陶瓷中由热双折射引起的空间分布局部去极化现象。我们发现，当陶瓷的厚度与晶粒尺寸相当时，局部去极化的变化急剧增加。

Thermally induced local-depolarization in thin YAG ceramics for high-power lasers

We investigate a spatially-distributed local-depolarization induced by thermal-birefringence for the power scaling in Nd:YAG ceramics. We found the variation of local-depolarization was dramatically increased when the thickness of ceramics becomes comparable to the grain size.
