Abstract

Photorefractive crystals have many applications in holographic storage, optical communications, and nonlinear optical information processing. One problem is that the photorefractive holographic index gratings can be erased in the readout process. Several non-destructive approaches have been proposed and demonstrated in different photorefractive materials. Based on the initial research of domain fixing on KNSBN crystals, we studied the high order harmonic gratings during electrical domain fixing process in KNSBN crystals. In this paper, we mainly focus on the properties of the first order and second order harmonic index gratings of Mn-doped KNSBN crystal during electrical domain fixing process at room temperature. Domain fixing in Rh:SBN was also investigated, and the results in Mn:KNSBN and Rh:SBN were compared. In Mn:KNSBN crystals, the second order harmonic grating becomes stronger after fixing. This may be the main reason of the high noise in the revealed grating, which affects the image quality and fidelity. In addition, the effect of the accumulated charges in the revealing process was also discussed.
