Abstract High efficiency self-pumped phase conjugation (SPPC) has been obtained in 45o-cut Rh:BaTiO3crystal using a Ti:AI2O3 laser. Stable SPPC reflectivities as high as 90% are measured in a region of incident angle between 45o and 67o. The SPPC buildup time is 5-7 times as fast as 0o-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 45o-cut Rh:BaTiO3is characterized and compared with the 0o-cut Rh: BaTiO3.
