摘      要：For a photorefractive crystal,the exponential gain coefficient of two-wave coupling,Г,is a *** this paper,the constantГof a LiNbO_(3):Fe crystal is measured by using Gaussian beams and quasi-uniform *** difference between the results is attributed to the self-defocusing effect of the crystal.
