As Estimation of Donor Concetration in LiNbO3:Fe Using the Photorefractive Effect

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 de...
