高功率激光光学系统和各种航天器的红外装置的发展对红外窗口和整流罩的材料提出越来越高的要求。天然晶体和原先使用的人工晶体的性质满足不了要求,研制出更优性能的新材料和改造原先使用的晶体材料使其具有更优的物理、化学特性是当前红外光学材料科学的
The development of infra-red devices for high power laser optics and various spacecraft has placed increasing demands on the materials of infrared windows and fairings. Natural crystals and the original use of the properties of artificial crystals can not meet the requirements, develop better performance of new materials and the transformation of the original use of crystalline materials to make it has better physical and chemical properties of the current IR optical material science
