Popis:	Results of an experimental investigation of optical field record created by photorefractive effect in iron doped LiNbO3, is presented in the paper. According to time dependences of record amplitude obtained at different intensities of recorded field it was shown that the standard model of process description should be modified by adding another level (trap level). A simple and approximative analyse of the suggested model with respect to experimentally obtained results allowed to estimate the concentration of occupied donor centres in investigated material.
