Abstract
Photorefractive self-pumped phase conjugation (SPPC) behavior is exami ned at 633 nm in cerium-doped barium titanate crystals. A reflectivity as high as 86.8% is reported. The buildup times are an order of magni tude faster than the corresponding values in Co:BaTiO3 and Cu:KNSBN cr ystals with similar input powers. A possible mechanism responsible for the high self-pumped phase conjugation reflectivities in the negative incident angle range is discussed.
