1970年到1975年间,在红外材料方面存在着一种不寻常的情况。受高功率激光光学系统的高透明度的透镜与窗口元件要求的驱使,在质量、物理强度与材料不同的尺寸中,取得了有意义的进展,特别是碱卤化物,硒化锌中,及在纤维光学应用的熔凝二氧化硅里。概述这些材料的现状,检查决定这些材料的光学与机械极限的基本物理过程,并为未来的电学与磁光材料的研究工作提出建议。 Between 1970 and 1975, there was an unusual situation with infrared materials. Driven by the high transparency of lens and window elements of high-power laser optical systems, significant progress has been made in the quality, physical strength and size of the materials, especially in alkali halides, zinc selenide and in Fused Silica in Fiber Optics Applications. Summarize the current status of these materials, examine the basic physical processes that determine the optical and mechanical limits of these materials and make recommendations for the future work on electrical and magneto-optical materials.
