    Realization of non-volatile holographic storage in LiNbO 3∶Cu∶Ce crystals with two illumination schemes is reported in this paper, one is with ultraviolet light for sensitization and red light recording proposed by Buse et al., and the other is with 458 nm blue light from Ar + laser for sensitization and red light recording. It is shown that the fixed (nonvolatile) diffraction efficiency and the fixing efficiency with the second scheme are higher than those with the first scheme, but the second scheme causes weakly light-induced scattering. When the optimal intensity of blue light is around 700 W/m 2, the nonvolatile refractive-index change is up to 5×10 -5.
