The velocity of surface acoustic waves in proton-exchanged 128°-rotated Y cut X propagation lithium niobate with a Cu or Al thin film deposited on the sample surface has been measured using acousto-optic techniques in a wide frequency range. The electrical and mechanical perturbations of the propagation surface introduced by the metal film affects the acoustic velocity, thus providing a mean for its accurate control.
