The acousto-optic deflector is used to scan a laser beam over a range of angles, or to control the output angle of a laser beam with great accuracy. A Bragg configuration produces a single first order output beam, whose intensity is directly linked to the power of the RF control signal, and whose angle is directly linked to the RF frequency. By varying the frequency of the RF control signal, the angle of the output laser beam is adjusted.

An acousto-optic deflector is defined by the following parameters:

A deflector is used to form a high number of "pixels" to scan laser beams.

Two deflectors can be used in series and at right angles, to provide a full two-dimensional Acousto-Optic X-Y Scanning Systems.

Acousto-optic deflectors require a variable frequency source able to cover a frequency range within 10MHz and 2GHz. EOPC offers several stock acousto-optic deflector drivers to choose from, as well as custom models.

Applications for acousto-optic deflectors include generating graphics, compensation of tracking errors in rotating polygon mirrors, optical tweezers (to trap atoms or molecules), two and three dimensional measurements and cavity dumping (high power laser pulses switched out of a laser cavity).
