Temperature Gradient Technique Grown Nd∶YAG Crystal for Heat Capacity Laser with Laser Output of 1200 W
【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%。
【Abstract】 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.Accordding 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%.
