| 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. |
