Abstract
The light-induced absorption coefficient Delta alpha and the light-int ensity dependence of the photorefractive parameters known as the effec tive trap density N-E, the mobility-recombination product mu tau(r) an d the photoconductivity sigma ph have been measured for four nominally pure BaTiO3 crystals. The qualitative correlation between Delta alpha , N-E, (mu tau(r))(-1) and sigma(ph) has been revealed. The results ar e explained by the two-center model of deep and shallow traps.
