Scandium oxide has proved to be a damage-resistant high-index material in laser coatings for use at 248 nm. The results of damage threshold measurements on laser reflectors and antireflection coatings of various designs, material combinations, and deposition temperatures are presented. The most significant effects are observed for overcoat layers on high reflectors and undercoat layers on antireflection coatings. Thresholds >6 J/cm(2) for 20 nsec pulses were observed in both cases.
氧化钪已被证明是一种用于248纳米激光涂层的抗损伤高折射率材料。本文给出了对各种设计、材料组合和沉积温度的激光反射镜和减反射涂层损伤阈值测量的结果。在高反射镜的外涂层和减反射涂层的底涂层中观察到了最显著的效果。在这两种情况下，对于20纳秒脉冲，均观察到阈值>6 J/cm² 。
