Abstract: In order to study nonvolatile holographic storage of near-stoichiometric Ce: Fe: LiNbO3 crystal,the spectrum of near-stoichiometric Ce: Fe: LiNbO3 crystal was tested.The results indicated that the infrared transmission spectra of the near-stoichiometric Ce: Fe:LiNbO3 crystal was narrower than that of congruent Ce:Fe:LiNbO3 crystal.the peak was located at 3466cm-1,and its ultraviolet spectrum shifted forward to violet.With single-photon and two-photon storage methods,nonvolatile holographic storage of near-stoichiometric Ce:Fe:LiNbO3 crystal was realized in theory and experiment.The results showed that in the single-photon storage experiments,the diffraction efficiency with the presence of mercury lamp became higher than that without mercury lamp.The performance in two-photon storage scheme was better than that in single-photon storage scheme.
