Abstract
Efficient production of surface acoustic waves using optical distributions controlled by spatial light modulators is demonstrated. The measurements presented used only 40 mW average optical power on the sample surface. It is shown that a spatial light modulator produces light distributions which control the surface acoustic wave generation on the sample surface; this can be used to produce similar light distributions to those formed by computer generated holography
