Abstract

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.
