摘要

Nd:GGG晶体是热容固体激光器的一种重要的工作介质.采用提拉法沿〈111〉方向生长出直径为60 mm的Nd:GGG单晶,利用应力仪、偏光显微镜和环境扫描电子显微镜及化学腐蚀等仪器和手段,对晶体的宏观和微观缺陷进行了观察和分析,可为改善生长工艺、生长大尺寸优质Nd:GGG晶体提供指导.

Abstract

Nd:GGG laser crystal is one kind of important active material of solid state heat capacity laser. Nd:GGG laser crystals grown by using the Czochralski method were about 60mm in diameter. The macroscopical and microcosmic defects were studied with stress meter, polarization microscope, ESEM and chemical etching method. Reference could be afforded to improve growth technological parameter and grow good large diameter Nd:GGG laser crystals.
