Abstract: We report on the light-induced absorption in undoped photorefractive Bi2TeO5 (BTeO) crystal. The so-called "two-center" model is shown to adequately describe the present material behavior. We demonstrate that nonlinear light-induced absorption occurs for high light intensities. The theoretical model allowed us to find out some material parameters from experimental data. We also investigate the effect of intensity and wavelength on the light-induced absorption.
