We develop a model that describes the effect of size distribution of nanoabsorbers on the subsurface of fused silica on laser-damage probability. Using Mie theory and heat equation, we obtain the correlation between the critical fluence and particle radius. Considering a power law distribution of nanoabsorbers, the curves of laser-damage probability are calculated based on experimental results of contents of contaminations and a fit parameter of size distribution of nanoabsorbers. This paper presents the influence of various potential candidates, jointly, on laser-induced damage.
我们开发了一个模型,该模型描述了熔融石英亚表面纳米吸收体的尺寸分布对激光损伤概率的影响。利用米氏理论和热方程,我们得到了临界能量密度与颗粒半径之间的相关性。考虑纳米吸收体的幂律分布,基于污染物含量的实验结果和纳米吸收体尺寸分布的拟合参数,计算了激光损伤概率曲线。本文介绍了各种潜在因素共同对激光诱导损伤的影响。
