Abstract

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.
