摘要：

Light-induced absorption in pure B12TiO20 crystal and crystals doped with Nd, Mo, W, and V was investigated using the pump-probe method. Q-switched frequency-doubled (532 nm) YAG:Nd laser with pulse duration similar to 20 ns was applied for sample irradiation. Investigation of pump-induced transmission was carried out by means of a tunable dye laser radiation at lambda (1)=568 nm and lambda (2)=698 nm. The dependence of the light-induced absorption coefficient on the pump beam intensity and probe wavelength was determined. The two-center model was used to explain the observed results.
