| Abstract: | It is reported the fist observation of mechanism transformation with pump beam incident angle and position of self pumped phase conjugation (SPPC) in BaTiO3:Ce crystal in the green,λ=514.5nm.It was found that the SPPC mechanism changed from a “cat”(FWM TIM) mechanism to a stimulated photorefractive backscattering and four-wave-mixing (FWM-SPB) when the pump beam incident angle and position were varied,with a transition of FWM-TIR and FWM-SPB mechanism coexist. |

| Keywords: | Self-pumped phase conjugation Reflectivity of phase conjugation SPPC formation mechanism |
