title: Beam coupling in photorefractive BaTiO(3) crystals.
abstract: Beam-coupling experiments are carried out with two BaTiO(3) crystals as a function of the intensity and wavelength. We demonstrate in these experiments that hole-electron competition is not the only mechanism responsible for the anomalous behavior of photorefractive BaTiO(3) crystals. We find that the intensity-dependent absorption coefficient plays a major role in beam-coupling experiments.
