title: Improvement of photorefractive properties and holographic applications of lithium niobate crystal.
abstract: Based on analyzing and synthesizing the effects of In doping, Fe doping and oxidation state, we propose an efficient way to improve photorefractive properties of LiNbO3 crystal. According to the proposed way, a sample of In:Fe:LiNbO3 crystal is grown and achieves larger dynamic range, higher sensitivity and better signal-to-noise ratio thanFe:LiNbO3 crystal (Fe:0.03wt.%) that is generally considered as a preferable storage medium for high-density holographic data storage. In a coherent volume 0.074cm3 of this crystal, 2030 holograms have been successfully multiplexed and exactly identified in a compact volume holographic data storage and correlation recognition system.
