Abstract
We present two-beam coupling experiments in the nanosecond regime at 1 .06 mu, using photorefractive BaTiO3:Rh. The maximum observed exponent ial gain coefficient is 14.2 cm(-1). No intensity-dependent electron-h ole competition and no strong saturation of the photoionized charge ca rriers are observed for intensities of less than 20 MW cm(-2). The ene rgy required for recording the photorefractive grating is not signific antly different in the nanosecond and the cw regimes. (C) 1997 Optical Society of America.
