By application of kinetic equations for photorefractive effect, the minimal H+ concentration for thermal fixing the photorefractive holograms in Fe∶LiNbO 3 and the relationship between H+ concentration and spatial frequency of holograms are derived. The H+ concentration of several samples are measured with spectrum comparison method. The range of H+ concentration for effective thermal fixing is obtained. Experiments of holographic storage and thermal fixing in Fe∶LiNbO 3 are finished and good experimental results of 100 h continuous nonvolatile read out are showed.
