Acoustooptic interaction for most effective deflection of unguided light via acoustic surface waves.
The light deflection efficiencies of surface acoustic waves propagating on YZ-LiNbO(3) crystal are examined for different geometrical configurations. The optimum one is found to be the back reflection geometry, with S polarization of the impinging light beam, where a figure of ~16% of the total deflected to undeflected light intensity ratio is easily attainable with a surface corrugation amplitude of about 50 A.
