Abstract

Zn:Fe:LiNbO₃ crystal has shorter response time and higher damage resistance ability than Fe:LiNbO₃ crystal because of the doping of Zn ions, and the diffraction efficiency in Zn:Fe:LiNbO₃ is comparable to that in Fe:LiNbO₃ crystal. Transmission holographic recording geometry has been taken for its larger attainable dynamic range and sensitivity than that of the 90-degree geometry. Although there is relatively strong fanning effect in transmission geometry, Zn ions in the co-doped Zn:Fe:LiNbO ₃ crystal can restrain the fanning effect effectively. In our experiment, 60 holograms were angularly multiplexed and 72 spots were spatially multiplexed without hologram fixing technology, and the holograms can be stored more than ten days. A storage density of 4Gbits/cm³ has been obtained. The whole writing/reading process was accomplished automatically.
