摘　　要：首次报道用国产光折变晶体BaTiO_6制成的反射率大于30%的自泵浦相位共轭镜(SPPCM).并使用它成功地完成了畸变像复原实验.文中给出了自泵浦相位共轭信号的建立与入射光强度.入射光和晶体晶轴夹角的依赖关系及其擦洗速率的实验结果.文中还首次提出了一种使用单块BaTiO_3晶体,使多束入射光同时获得各自相位共轭波的方法.In this paper, we report for the first time the a aelfpumped phase conjugate mirror (SPPCM) with reflectance of more than 30 % has been made using photorefrao-tive crystal BaTiO3 grown in China. An experiment to recover a distorted image has been performed successfully using this mirror. Both the built-up process of the self-pumped phase conjugate signal, which depands on the intensity of the incident beam, and the angle between the incident beam and the crystal axis and the erasure rate of the SPPOM have been measured. We report also for the first time a device which can generate bwo or more reflected phase conjugate signals simultaneously for two or more incident beams respectively using only one SPPCM.
