Effect of Li/Nb ratio on holographic storage properties of In:LiNbO 3 crystals
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 ultraviolet–visible absorption spectra. The holographic storage properties of In:LiNbO 3 crystals were investigated by tw...

crystals were investigated by two‐wave 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. © 2007 Wiley Periodicals, Inc.
