Doping CuO, Ce2O3 and In2O3 in LiNbO3, In:Ce:Cu:LiNbO3 crystals have been grown by the Czochralski method. The infrared spectra were measured and the mechanism of the violet shift of OH absorption peak was investigated. In In:Ce:Cu:LiNbO3 crystal, Cu and Ce locate at the deep level and the shallow level, respectively. The two-photon holographic storage was realized in In:Ce:Cu:LiNbO3 crystal by using He-Ne laser as the recording light and ultraviolet light as the gating light. The recording time of In:Ce:Cu:LiNbO3 is 30 min, which is 10 min shorter than that of Ce:Cu:LiNbO3.
