Abstract
The phenomenon of acousto-optical interaction is shown by a simple experiment. Using an acousto- optic modulator recycled from a dismantled industrial laser, a laser pointer, and minimum control electronics, the action of a sound wave injected on the modulator generates the Bragg and Naman- Nath diffraction regimes, depending on the geometry chosen for the interaction between the laser beam and the modulator.
