摘要
对温升引起的激光窗口热应力分布和位相变化进行了分析 ,以 Ca F2 激光输出窗口为例 ,分别计算了表面强迫对流冷却下光强线型分布、高斯分布和均匀分布时窗口温升、相应的热应力分布和附加相移分布 。
In this paper,thermal stress and phase change induced by temperature rise of laser window are analyzed.Under convectiv e cooling system,the distribution of temperature increment,thermal stess and pha se change are calculated in the case of different intensity profile (line,gauss, uniform) with CaF 2 laser output window as a example.The influence of distribu tion of intensity on thermal effect is discussed.
