Abstract

The holographic properties of doubly doped lithium niobate crystals with Indium have been investigated. It is found that doping slight Indium concentration (0.5mol%) in LiNbO₃:In, Fe crystal can efficiently increase the sensitivity with small dynamic range changing. To improve the whole holographic properties of LiNbO₃ crystal, LiNbO₃:In, Fe with ideal doping concentrations and a new photorefractive material LiNbO₃:In, Mn have been proposed and achieved larger dynamic range, higher sensitivity and better signal-to-noise ratio than LiNbO₃:Fe crystal (Fe:0.03wt.%) that is generally considered as a preferable storage medium in holographic memories. In a common volume of LiNbO₃:In, Fe crystal proposed, 2030 holograms have been successfully multiplexed and exactly identified in a compact volume holographic data storage and correlation recognition system.
