| 摘 要： | 研究了多种Rh:BaTiO3和Ce:BaTiO3晶体样品的受激背向光折变散射自抽运相位共轭特性和响应时间特性.结果表明，入射光与晶体a面或b面法线的夹角较大时，自抽运相位共轭光有更高的反射率、更快响应时间.利用前向二波耦合特性和相向二波耦合特性对实验现象给予合理的解释.实验结果表明，多数Ce:BaTiO3晶体比Rh:BaTiO3晶体的共轭光反射率高.

| Abstract: | Characteristics and response times of the stimulated photorefractive scattering self-pumped phase conjugator(SPS-SPPC) in the series of Rh-doped and Ce-doped BaTiO3 crystals are investigated.The experimental results show that the SPS-SPPC has higher reflectivity and faster response rate at greater incident angle.The phenomenon was properly analysed using characteristics of two-wave mixing.By the way,the phase conjugation reflectivity of Ce:BaTiO3 is higher than that of Rh:BaTiO3 crystals'. |

| Keywords: | BaTiO3 crystal two-wave mixing self-pumped phase conjugator response time |
