Holographic recording experiments of doubly-doped LiNbO3:Fe:Ni crystals were conducted by three kinds of different two-color recording schemes. The results show that the saturation diffraction efficiency, the fixing diffraction efficiency, and the recording sensitivity of oxidized LiNbO3:Fe:Ni crystal are higher than those of other reported doubly-doped LiNbO3 crystals. Based on the doped energy-band diagram, the effect of microcosmic optical parameter of the deep trap center on holographic recording properties of doubly-doped LiNbO3 is analyzed theoretically. LiNbO3:Fe:Ni has the potential of being a new highly efficient nonvolatile holographic recording material.
