Zn ions were added into melts with 4.0mol.%, Fe ions were with 0.02mol.%, and In ions were with varying concentration of 0, 1.0, 2.0 and 3.0mol.%. A series of Zn:In:Fe:LiNbO3 Crystals were grown by Czochralski technique. Their absorption spectra and photo-damage resistant ability were measured. The mechanism of the shift of OH- absorption peak was investigated. Their photorefractive properties were experimentally investigated by using two-beam coupling. The results shown that, the photo-damage resistant ability of Zn(4mol.%):In(3mol.%): Fe(0.02mol.%):LiNbO3 Crystals were two orders than that of magnitude higher than that of Fe:LiNbO3 crystals, and with concentration of Zn and In ions increasing, diffraction efficiency and response time of crystals were shortened. The experiment of associative memory were also carried out with Zn(4mol.%):In(3mol.%):Fe(0.02mol.%):LiNbO3 crystals for the recording device and with Zn(4mol.%):In(2mol.%):Fe(0.02mol.%):LiNbO3 Crystals for phase conjugation.
