描述了评价窗口材料的标准,并对Ge,GaAs,ZnSe和KCl四种材料作了比较,发现KCl具有最佳的光学特性,并设计制备了性能优良的减反射膜,测量了它们的吸收和激光损伤阈值.

Appropriatre figure of merit for describing a meterial used for a high power laser window has been pressented. And characteristics comparisons of four materials including Ge, GaAs, ZnSe and KCl have been made. The optical element made from the single crystals of KCl urned out to have good performance. An antireflection coating with low absorptance and high laser damage threshold has been designed and prepared.
