Abstract
In:LiNbO~3~ crystals with different Li/Nb ratios in the melts (Li/Nb = 0.94, 1.0, 1.1, 1.2) have been grown. The changes of the crystal structure on the Li/Nb were analyzed by the ultravioletβvisible absorption spectra. The holographic storage properties of In:LiNbO~3~ crystals were investigated by twoβwave coupling technique. The diffraction efficiency, response time, and photoconductivity of the crystals were measured. With increase in the ratio of Li/Nb, the diffraction efficiency decreases, the response time shortens, and the photoconductivity increases. Β© 2007 Wiley Periodicals, Inc.
