Abstract
The impurity absorption model is used to describe the experimentally observed reversible changes in the optical absorption spectrum induced in the Bi12TiO20:Al crystal by subsequent exposition to short-wavelength radiation with λi, = 532 nm and longer-wavelength radiation with λn changing from 588 to 1064 nm. The model takes into account the photoinduced transitions between two metastable states of a deep defect center leading to the change of its position in the crystal lattice under conditions of strong lattice relaxation.
