Description/Abstract

We present experimental data for the intensity-dependent absorption coefficient of a photorefractive "blue" sample of rhodium-doped BaTiO3 using beams of different wavelengths. A numerical photorefractive two-level model incorporating dual-wavelength illumination and a secondary photorefractive centre gives good agreement with experiment. We deduce values for the number densities, photoionisation cross-sections, thermal ionisation rate and recombination coefficients of the photorefractive centres. In this sample we determine that there is the usual deep trap concentration of ~ 2x10.
