title: Two-wave mixing in photorefractive BaTiO(3):Rh at 1.06 mum in the nanosecond regime.
abstract: We present two-beam coupling experiments in the nanosecond regime at 1.06 mum , using photorefractive BaTiO(3):Rh. The maximum observed exponential gain coefficient is 14.2 cm(-1) . No intensity-dependent electron-hole competition and no strong saturation of the photoionized charge carriers are observed for intensities of less than 20MW cm(-2) . The energy required for recording the photorefractive grating is not significantly different in the nanosecond and the cw regimes.
