In this article, the double‐doped Hf:Ce:LiNbO 3 crystals were grown by the Czochralski method and its photorefractive properties were systematically studied. Samples were treated with different oxidation/reduction. The photorefractive properties of Hf:Ce:LiNbO 3 crystals were investigated by the two‐beam coupling method. The results shown that the photorefractive properties of Hf:Ce:LiNbO 3 crystals were improved as compared with that of Ce:LiNbO 3 crystals. The oxidation/reduction treatment had great effect on the photorefractive properties and the doping mechanism was also discussed. © 2008 Wiley Periodicals, Inc.
