摘要
用温度梯度法生长了直径为75mm大尺寸的Nd∶YAG激光晶体,通过退火排除了生长过程中进入晶体的碳原子.用正交偏光显微镜观察了晶体的核心分布以及生长条纹.测试了室温下的吸收谱并利用吸收谱研究了Nd离子在YAG晶体中的分布.比较了温度梯度法与提拉法生长晶体的区别.
Large size （Ф75mm） high quality Nd：YAG crystals were grown by the temperature gradient technique（TGT）. The carbon atoms ,sere eliminated after 02 annealing. We have studied the core distribution and growth stripes by Zygo interferometer and orthogonal polarization microscope. The absorption spectra of Nd ： YAG crystal at room temperature have been measured. The distribution of Nd ions in Nd ： YAG crystal were studied by using absorption spectra. A comparison of temperature gradient technique and Czochralski （Cz） grown Nd：YAG crystals was made.
