Intensity-dependent absorption and its modelling in infrared sensitive rhodium-doped BaTiO<sub>3</sub>
We investigated the intensity-dependent absorption coefficient of photorefractive Rh:BaTiO<sub>3</sub> from the maximum (633 nm) to the near infra-red end (1.06 µm) of this crystal's sensitivity. A numerical photorefractive model, incorporating dual-wavelength illumination and a sec...

| 520 | |a We investigated the intensity-dependent absorption coefficient of photorefractive Rh:BaTiO<sub>3</sub> from the maximum (633 nm) to the near infra-red end (1.06 µm) 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. | ||
