非相干光作用下的Ce:BaTiO_3自泵浦相位共轭镜特性

Properties of Ce∶BaTiO 3 Self Pumped Phase Conjugator under the Interaction of Incoherent Erasure Beam

对ＣｅＢａＴｉＯ３晶体的自泵浦相位共轭镜在非相干光作用下自泵浦相位共轭反射率增强的特性进行了研究。实验是在Ｈｅ－Ｎｅ激光产生稳态自泵浦相位共轭输出后，用非相干光平行ｃ轴照射来获得这一增强特性的。当水平移动非相干光入射位置，发现有两个区域非相干光作用能使相位共轭反射率增加，本文对此进行了相应的分析和讨论。

The Output property of phase conjugation enhanced by the effect of incoherent erasures upon Ce∶BaTiO 3 self pumped phase conjugator is studied. This result is experimentally achieved by using incoherent beam illumination along the c axis  direction of the crystal when a He Ne laser generates steady phase conjugate signal. In the cases of the incident position of the erasure beam gradually movement, it is found that the reflectivities are increased by incoherent erasure beam. The results is analyzed and discussed.
