Influence of post‐treatment conditions on photoreactive effect of Zn:Fe:LiNbO 3 crystals

Three kinds of different Zn:Fe:LiNbO 3 wafers are prepared by proper reduction or oxidation post‐treatment processes. The optical‐damage‐resistance abilities and photorefractive properties are studied using the optical compensator technique and two‐wave coupling measurement, respectively. The holographic storage properties, that is, diffraction efficiency, writing time, erasure time, photorefractive sensitivity, and dynamic range, are also measured or calculated. The analyses indicate that the sample disposed by reduction is the most proper media for holographic storage application. © 2006 Wiley Periodicals, Inc.
