Paper Abstract

The effect of dopants in doubly-doped LiNbO3 crystals on persistence of two-center recording is investigated experimentally and theoretically in this paper. Six kinds of doubly-doped LiNbO3 crystals are used in experiments with 633nm recording and 404nm sensitizing, the results show that LiNbO3:Ce:Cu crystal has the largest persistence. The dependence of persistence on bulk photo-voltaic coefficient and photo-excitation coefficient of deep center for recording light (K12 and S12) is discussed based on jointly solving the two-center material equations and the coupled-wave equations. The results show that both the increase of S12 and the decrease of K12 will result in the decrease of the persistence. When a holographic storage system is designed, the appropriate dopant will help to obtain the high persistence and dynamic range simultaneously.
