摘要
分析了激光晶体热效应的影响因素, 利用热传导方程推导出激光晶体由于内部温度分布不均匀造成的端面热形变与晶体表面积的关系.针对普通圆棒晶体和螺纹棒晶体, 分别计算了它们的热形变和热焦距, 结果表明螺纹棒晶体可有效地改善激光晶体的热效应.
Abstract
The influence factors of the thermal effect of laser crystal were analyzed.Using the heat conduc-tive equation, the relationship between area of surface and thermal change of end face caused by the asymmetry distribution of inner temperature was deduced.The thermal distortion and thermal focus of common columni-form crystal and grooved crystal were calculated, respectively.And the results indicate that the thermal effect of laser crystal can be effectually improved by using the grooved crystal.
