Laser-induced damage experiments on and thin films were performed with 500 fs pulse duration at 1030 nm wavelength. Threshold fluences as a function of beam size have been determined for effective beam diameters ranging from 40 to 220 µm, in a single shot regime. The results suggest no beam-size effect related to material properties in the investigated range, but size effects related to the metrology. The results indicate the importance of appropriate focusing conditions and beam measurement to qualify the optics for use in lasers with large beam sizes.
在波长为1030nm、脉冲持续时间为500fs的条件下，对[具体薄膜名称1]和[具体薄膜名称2]薄膜进行了激光诱导损伤实验。在单次照射模式下，针对有效光束直径在40至220μm范围内的情况，确定了阈值通量与光束尺寸的函数关系。结果表明，在所研究的范围内，不存在与材料特性相关的光束尺寸效应，但存在与计量相关的尺寸效应。结果表明，合适的聚焦条件和光束测量对于鉴定用于大光束尺寸激光器的光学元件非常重要。
