本文介绍有附加反射镜组成的ＫＮｂＯ＿３：Ｆｅ环形腔自泵相位共轭器，实验测量了自泵相位共轭反射率η＿ｃ，随入射角ａ，环形胶光束夹角２θ和入射光强Ｉ＿４的关系，并给出了随时间变化过程中光束间的能量转移现象。
In this paper, the self-pump phase conjugator of KNbO_3: Fe ring cavity with additional reflector is introduced in this paper. The self-pump phase conjugate reflectivity η_c is experimentally measured. With the incident angle a, the relationship between the included angle 2θ and the incident light intensity I_4 , And gives the phenomenon of energy transfer between the beams over time.
