This paper presents the diffraction efficiency of two-wave mixing in Fe-LiNbO3 (up to-76%) through low frequency modulating one light beam, which is twice greater than the diffraction efficiency (30%) without modulation. Our theoretical analysis of moving grating is. used to explain the experimental results.
