激光诱导损伤是制约大型激光设备光学器件寿命的关键因素。对熔融石英进行了损伤阈值测试，确定了两种不同孔径的激光设备对熔融石英的损伤阈值。损伤阈值表示部件的边角抗损伤能力较弱。角上的酸蚀不能有效地提高损伤阈值。提出了一种基于统计的小孔径试验阈值外推模型，以预测功能条件下的损伤阈值。
Laser-induced damage is a key lifetime limiter for optics in large laser facilities. Fused silica is tested to find the damage threshold on two different laser facilities of different apertures. The damage threshold shows that the corners of the component are less damage resistant. The acid etch on a corner does not effectively increase the damage threshold. A statistics-based model is presented to extrapolate the threshold data in a small-aperture test to predict the damage threshold under functional conditions.
