| Abstract: | Incident with high speed amplitude modulated beam, the properties of self-pumped phase conjugation (SPPC) and mutually pumped phase conjugation (MPPC) coexisting are investigated in a slow response Cu:KNSBN crystal. The effect of modulating frequency and incident position to reflectivity is given. The results indicate that the phase conjugate beam of photorefractive SPPC and MPPC coexisting for high speed amplitude modulated beam can transmit information without distorting,so it can be applied in the encode communication and information processing. |

| Keywords: | High speed amplitude modulated beams SPPC and MPPC coexisting Reflectivity of phase conjugation |
