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'.
