ABSTRACT:
A process for acousto-optic modulation of a monochromatic light beam, delivered by a laser, consists in deflecting the light beam in an acousto-optic modulator which receives a composite electric signal. The composite signal has at least one modulation frequency. It further includes two compensation components. The overall acoustic power applied to the modulator is maintained at a substantially constant value by servo-controlling the electric power of the two compensation components having frequencies which are mutually different and different from the modulation frequency or frequencies.
