Abstract High efficiency self-pumped phase conjugation (SPPC) has been obtained in 45^o-cut Rh:BaTiO₃crystal using a Ti:AI₂O₃ laser. Stable SPPC reflectivities as high as 90% are measured in a region of incident angle between 45^o and 67^o. The SPPC buildup time is 5-7 times as fast as 0^o-cut Rh: BaTiO₃ crystal. Reflectivity as a function of wavelength is also obtained. The reflectivity remains essentially constant at 9±3% from 708 to 858nm. The photorefractive performance of this special 45^o-cut Rh:BaTiO₃is characterized and compared with the 0^o-cut Rh: BaTiO₃.
