Reduction of the temporal fluctuation of the signal intensity in an optical wave-mixing system with a reflection grating is studied by use of a feedback of the output pump with appropriate feedback reflectivity. The advantage of the method is that the temporal fluctuation of the output intensity can be significantly reduced, although its mean intensity is not reduced.
