Abstract. The light-induced absorption coefficient Δα and the light-intensity dependence of the photorefractive parameters known as the effective trap density NE, the mobility-recombination product μτr and the photo- conductivity σph have been measured for four nominally pure BaTiO3 crystals. The qualitative correlation between Δα, NE, (μτr) -1 and σph has been revealed. The results are explained by the two-center model of deep and shallow traps.
