Paper Abstract

We have studied theoretically the steady-state nonvolatile two-step, two-color holographic recording performance for both the congruent and the near-stoichiometric LiNbO3:Fe based on the two-center model (the deep-trap and the shallow-trap centers are Fe2+/Fe3+ and NbLi4+/NbLi5+, respectively). We compare the amplitudes of the total space-charge fields and the recording sensitivities between the congruent and the near-stoichiometric LiNbO3:Fe. The results show that the amplitudes of the total space-charge fields in near-stoichiometric LiNbO3:Fe are larger than that of congruent ones by at least one order of magnitude, while the recording sensitivities of the near-stoichiometric LiNbO3:Fe are confirmed theoretically to be around two-order in magnitude higher than that of the congruent ones with the same experimental conditions at low intensity region.
