The acousto optic interaction on proton-exchanged 128°-rotated Y-cut LiNbO_3 wats investigated to evaluate the photo-elastic constants. The experimental and theoretical analysis using a surface acoustic wave of 200 MHz and a He-Ne laser beam showed that the acoustic power required for 100% diffraction depends on the proton-exchange depth and that the photo-elastic constants of the proton-exchanged layer are 76% of those in unexchanged LiNbO_3. The effects of annealing on the photo-elastic constants and the diffraction efficiency were also measured.
