Abstract

Measurements of the angular dependence of the efficiency of light diffraction by acoustic surface waves on crystalline quartz are presented. From these and other measurements on LiNbO₃ it is concluded that the largest diffraction efficiencies obtainable at present from acoustic surface waves are on the order of a few percent except in the special configuration where Bragg diffraction can be utilized. The significance of these measurements with respect to the operation of practical light deflection devices is discussed.
