本文首次用两台He-Ne激光器在光折变晶体BaTiO3：Ce中实现了桥式工系浦位共轭，并实验确定了工系渝光的最佳人射角度。对BaTiO3:Ce桥式互泵辅相位共轭镜的形成机理作了分析，并对实验的结果和现象进行了讨论．
In this paper, the bridge-type POS conjugation was achieved by using two He-Ne lasers for the first time in the photorefractive crystal BaTiO3: Ce. The best angle of incidence for the Yu-Guang department was determined experimentally. The formation mechanism of the BaTiO3: Ce bridge-coupled auxiliary phase conjugate mirror was analyzed, and the experimental results and phenomena were discussed.
