Abstract

Laser induced damage (LID) experiments were performed with a 2-J frequency-multiplied Nd:YAG laser at 1/2 /spl mu/m wavelength and a variety of metal mirrors (pure and impure diamond-turned) at shallow angle of incidence to study the sensitivity of these mirrors to LID under long term exposure. Practical lifetime curves for Al-1100 and 99.999% pure Al mirrors have been established up to 10/sup 4/ shots of operation. The results show general agreement with theoretical predictions.

浅入射角长期照射下金属反射镜的激光损伤

利用波长为1/2 /spl μ m的2 j倍频Nd:YAG激光和浅入射角的多种金属反射镜(纯金刚石和不纯金刚石转动)进行激光诱导损伤实验，研究这些反射镜在长期照射下对激光诱导损伤的敏感性。建立了Al-1100和99.999%纯Al反射镜在10次/次/次运行时的实际寿命曲线。结果与理论预测基本一致。

期刊介绍： 19th-Century Music covers all aspects of Western art music between the mid-eighteenth and mid-twentieth centuries. We welcome--in no particular order--considerations of composers and compositions, styles, performance, historical watersheds, cultural formations, critical methods, musical institutions, ideas, and topics not named on this list. Our aim is to publish contributions to ongoing conversations at the leading edge of musical and multidisciplinary scholarship.
