This study aims to calculate the induced absorption coefficient in the photorefractive crystals (Bi12 SiO20). A theoretical model was proposed and by using mathcad14 program the results were obtained .The average of induced absorption coefficient (α) was highest at (420 cm-1). Through using the proposed program, the induced absorption coefficient was found theoretically then compared with the experimental results through different situations. The exciting wavelengths of laser were 530, 500mm. It is noticed that the practical results conforms with the theoretical ones. The induced absorption coefficient increases with the increasing the applied powers. Practically, different laser rays of various wavelength have been focused on the crystal BSO. The spectrometer was used to get the spectrum of each wavelength and then the spectrum of crystal was found without radiation . Using a laser generator (Parametric light generator LТ-2215), different wavelengths were obtained (520, 530, 545, 580, 590, 600) nm. The induced absorption coefficient increases when the exciting wavelength decreases, where the influential wavelength was 520nm.
