초록

Mutually pumped phase conjugator(MPPC) is experimentally investigated and analyzed in terms of fanning gratings of a photorefractive BaTiO$_3$ crystal. As considering the intensity-dependent absorption and coupling cofficients in photorefractive two wave mixing, the dependence of phase conjugate reflectivites on the incident angle, beam ratio, and total intensity in MPPC is analyzed.
