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