Abstract
Illumination of a photorefractive BaTiO3 crystal provides an induced a bsorption increase, which is explained by the two-center charge transp ort model. Detailed investigations of buildup and decay of light-induc ed absorption are performed. Intensity changes of the incoming wave ar e attenuated by these absorption changes. The requirements for distinc t intensity stabilization are theoretically estimated. Intensity stabi lization is experimentally demonstrated, and a decrease of the intensi ty fluctuations of as much as 30% has been achieved.
