The predicted [A. M. Dykhne and B. P. Rysev, Poverkhnost', fizika, khimiya, mekhanika, No. 6, 33 (1983)] linear, resonant growth in the amplitude of a surface elastic wave in a solid excited by the absorption of laser radiation, scanned at the velocity of surface waves, focused on the surface is observed experimentally. The dependence of the amplitude of the surface wave on the scanning velocity, the dependence of the amplitude at resonance and the width of the resonance curve on the scanning length and intensity of the radiation are obtained. The results presented agree well with the theory.
