摘要：
The steady-state nonvolatile two-step, two-color holographic recording performance with continuous-wave lights for LiNbO3 : Fe: Mn was studied theoretically based on the two-center model. By comparing all of the different electron transfer processes between the deep-trap centers (Mn2+/Mn3+) and the shallow-trap centers (Fe2+/Fe3+), our results show that the direct electron exchange between the Mn2+/Mn3+ and the Fe2+/Fe3+ levels due to the tunneling effect dominates the amplitude of total space charge Field under different experimental conditions in LiNbO3 : Fe : Mn. This direct electron transfer process also plays a key role in the two-step, two-color holography performance of the crystal.
