摘　　要：用温度梯度法(TGT)生长了大尺寸的Nd∶YAG激光晶体,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。根据热容激光的原理,利用生长的Nd∶YAG激光晶体片设计了热容激光器,利用侧面抽运,获得了1200 W的激光输出,工作时间为2 s,光-光转换效率为30%。Large sized high quality Nd:YAG crystal was grown by the temperature gradient technique (TGT) method. The absorption spectra of Nd:YAG crystal at room temperature were measured. The distributions of Nd ions in Nd:YAG crystal were studied by using absorption spectra. According to heat capacity laser theory, a heat capacity laser by using this Nd:YAG crystal was designed and fabricated with the laser output of 1200 W and the optical-optical conversion efficiency of 30%.
