Abstract:	Bismuth germanate Bi3Ge4O12 (BGO) single crystals doped with ruthenium, manganese and ruthenium plus manganese are gown by Czohralski technique with automatically diameter-weight control method. The effect of doping on the light-induced, magneto-optical and holographic properties of BGO single crystals is studied. It was found that the optical transmission spectrum of doped samples is modified strongly under thermal annealing and homogeneous illumination with UV light as well as the photochromic effect is fully reversible. The magneto-optical rotation was measured and Verdet constant was calculated at visible spectral range. Holographic grating are successfully recorded at 633 nm.
