title: Enhanced stimulated photorefractive scattering self-pumped phase conjugator in Ce-doped BaTiO 3 with external mirrors.
abstract: The characteristics of stimulated photorefractive scattering self-pumped phase conjugator (SPS-SPPC) in BaTiO3 :Ce crystal without and with an external mirror have been studied and compared. The experimental results show that the SPS-SPPC becomes unstable at a larger incident angle. An additional external mirror can create a stable optical path in the crystal and improve the stability of the SPS-SPPC effectively, and, at the same time, it can enhance the response rate and the phase conjugate reflectivity as well. We offer a reasonable explanation of the experimental results by using a semilinear cavity model.
