摘要
（Ｎｄ，Ｔｂ，Ｃｅ）：ＹＡＧ晶体是我们最近研制的一种新激光晶体。本文将给出在风冷条件下，（Ｎｄ，Ｃｅ）：ＹＡＧ和常用的Ｎｄ：ＹＡＧ及（Ｎｄ，Ｃｅ）：ＹＡＧ在不同重复频率下的激光输出，束散角和光束质量因子的测试结果。对比这些结果，可以看到（Ｎｄ，Ｔｂ，Ｃｅ）：ＹＡＧ晶体的效率不低于（Ｎｄ，Ｃｅ）：ＹＡＧ，而在热畸变和热稳定性方面，明显优于Ｎｄ：ＹＡＧ和（Ｎｄ，Ｃｅ）：ＹＡＧ。
Nd,Tb,Ce): YAG crystal is a new laser material developed recently.In this paper,the comparission research on the laser output properties, for example laser output energy, beam divergence angle and beam quality factor M2, with other laser crystals, such as present Nd:YAG and (Nd,Ce): YAG crystal, is reported.The experimental results show that the pulsed laser effectiveness of (Nd,Tb,Ce):YAG crystal may not be lower than other crystal's, but the thermal distortion and the thermalstability of(Nd,Tb, Ce): YAG crystal are obviously better than other crystal's,under the condition ofblowing cooling. The crystal can be used in high repitation frequency laser.
