AOQS - Acousto-Optic Q Switches
Benefit from high-quality optical materials and high-damage threshold coatings for high-power intracavity pulse control applications.
Applying RF power to an acousto-optic q-switch diverts most of the incident laser light out of the main beam path and spoils the Q of the laser cavity. This allows high gain to build up. Coherent AOQS devices feature high modulation loss and low insertion loss.
