摘要
We report single-shot damage threshold as a function of pulse duration (50-900 fs) for MgF2/ZnS 800-nm omnidirectional-reflection film, interference filter, and gold film. The results indicate that the damage with ultrashort pulse is nonthermal, which is different from that with long pulse. Additionally, the ablation crater depths of 45° high-reflection film and interference filter are presented. A logarithmic relation between the ablation depth and pulse fluence, which is similar to that of transparent materials, is found.
