Abstract

The results of experimental investigation of light induced absorption in Bi₁₂TiO₂₀ single crystals with different stoichiometric composition are presented. We study the dynamic of the changes in absorption coefficient of Bi₁₂TiO₂₀ single crystals grown from different melt composition for the incoherent light with the wavelength of λ ≈ 660 nm. It was shown that the change in light absorption reaches the values of ~ 0.4 cm^-1 in the crystal containing 7.5 mol.% TiO₂ in the start melt composition.
