In this paper, the nonlinearities resulting from the simple band transport model of photorefractivity are compared with dependences experimentally obtained in LiNbO3:Fe crystals. The investigation of nonlinearities is performed for both periodic and aperiodic optical fields. The comparison shows that the space-charge field cannot be the main cause of light-induced refractive index changes.
