摘要：

We investigate the intensity-dependent absorption coefficient of photorefractive Rh:BaTiO3 from the maximum (633 nm) to the near infra-red end (1.06 mu m) of this crystal's sensitivity. A numerical photorefractive model, incorporating dual-wavelength illumination and a secondary photorefractive centre, gives good agreement with experiment and shows that such a two-centre model is sufficient to explain the results obtained in the visible and infrared wavelength region.
