Description/Abstract

We report on photoinduced, intensity dependent absorption in "blue" rhodium doped BaTiO3. The change in absorption, observed under illumination by visible or infrared radiation, has successfully been modelled. Agreement obtained between theory and experiment indicates that the shallow trap model can effectively characterise the intensity dependent behaviour at red and infrared wavelength, and can be used to calculate essential photorefractive parameters in this important wavelength range for diode-laser applications
