Acousto-Optic Q-Switches
The Acousto-optic Q-switch is a special modulator that introduces high repetition frequency loss in the laser cavity. Rather than being continuous-wave output, it causes the output to be composed of a series of light pulses with extremely high peak power and short pulse duration. The Q-switch allows efficient control of Q factor, initial pulse suppression, has high working efficiency, allow quick and easy adjustments, and have good stability. It is used in laser engraving, scribing, cutting, fine processing and other applications that require high laser intensities.
