摘　　要：介绍有附加反射镜组成的KNbO_3:Fe环形腔自泵相位共轭器,实验演示了相位共轭光建立过程中各光束间的能量转移现象,并测得自泵相位共轭反射率R随入射角α、环形腔光束夹角2θ和入射光强I_4的依赖关系,在最佳条件α=23°和2θ=20°时,测得最大的相位共轭反射率R=36%。The KNbO_3:Fe self-pumped phase conjugation in a ring cavity with two additional reflected mirrors is presented in this paper. During the build-up of phase conjugate light the time evolution of different light beams with energy transfer was experimentally demonstrated. The self-pumped phase conjugation reflectivity R as a function of the incident angle α, the light beam intersecting angle 2θ for ring cavity and incident light intensity I_4 was measured. Under the optimal condition α=23° and 20=20°, the maximum phase conjugation reflectivity was obtained to be R=36%.
