Abstract
Large optically homogeneous photorefractive Bi12TiO20 single crystals doped with Al, P, Ag, Ctl, Co and Al + P are obtained by the top seeded solution growth method in a Bi2O3 solution. A strong bleaching effect is observed a t Al, P, Ag and Al + P doped crystals, whereas doping with Cu and Co induce d a strong photochromic effect and increased the absorption coefficients in a red spectral region. Al, P and Al + P doped crystals increased the value s of optical rotation power, while Cu and Ag-doped crystals lead to strong decreasing of optical activity in comparison with non-doped Bi12TiO20.
