摘要

The properties and applications of the photorefractive two-wave coupling in congruent SBN:Cr (Sr_0.61Ba_0.39Nb₂O₆:Cr) crystal under external dc electric field are experimentally investigated in this paper. The variation of the intensity gain coefficient of the two-wave coupling with the external field is analyzed, and the measurement results are presented. It is found that the photorefractive two-wave coupling gain and response rapidity can be both increased, by applying appropriate external electric field to the crystal. Further study indicates this electric response property of SBN:Cr crystal is useful to some applications, such as improving the image edge-enhancement and the image edge-enhancement joint-transform correlator based on the nonlinear energy transfer of photorefractive two-wave coupling in the crystal.
