摘　　要：从研究目前热门的激光晶体Nd∶YVO4应力双折射入手,研究了其对激光非线性输出的影响。通过实验发现,激光晶体的应力双折射虽然很小,但是一定的应力双折射会导致激光的非线性输出。通过实验掌握了一套方法,可挑选质量好的激光晶体,以便获得稳定的激光输出。The stress of the Nd：YVO4 and how it affecting the non-linear output of the laser is studied. Experimental results show that the stress birefringence of the crystal can affect the non-linear output of the laser though thestress is very little. How to select high quality laser crystal in order to get steady output is found.

关 键 词：激光晶体 ND:YVO4 应力双折射 非线性输出 线性输出
