We studied some factors affecting the properties relevant to nonvolatile hologram storage by using two-color recording scheme in In(0,1mol.%):Fe:Cu:LiNbO3 crystals. Two-color recording is achieved by use of 488nm blue light acts as the sensitized light and 633nm red light acts as the recording light. First, the effect of In3+ doping on the nonvolatile photorefractive properties was investigated experimentally. Next, the influences of the pre-illumination processing, the red-to-blue intensity ratio as well as the oxidation-reduction treatments on the nonvolatile photorefractive properties of In(1mol.%):Fe:Cu:LiNbO3 crystal were studied in detail.
