分析了晶体的不同切割方式对形成自泵浦位相共轭输出的影响,报道了晶轴与晶面成18°角的Ce:KNSBN晶体自泵浦位相共轭输出特性,实验证实了共轭反射率与入射角和入射位置有关,并得到反射率为57.16%的共轭输出。共轭光的形成时间随入射光强的增大而缩短。

The dependence of the output of self pumped phase conjugation (SPPC) on the different cutting methods of Ce:KNSBN crystal is analysed. The conjugate reflectivity up to 57.16% in a Ce:KNSBN crystal with a 18° angle between crystal axis and crystal surface is reported at a 514.5 nm Ar + laser. The phase conjugate reflectivity is proved connecting with the incident angle and incident position by experiments. Increasing the incident intensity, the response time of SPPC is demonstrated decreasing.
