Acousto-Optic Q-Switches

Fast intracavity optical switches for generating short laser pulses with high peak power.

Supplier: Isomet

Technology type: Acousto-Optics

Isomet's acousto-optical Q-switches (AOQS) are specifically designed for use as fast intracavity switches for high optical powers and short laser pulses. As part of the laser resonator, they are used as so-called loss modulators. When radiofrequency (RF) power is applied, the laser is "off" - but if the RF power is briefly removed, the laser emits a short pulse.

In-house production facilities such as crystal growing, optical polishing, anti-reflective coatings, vacuum-bonding and in-house electronics development are the basis for the production of sophisticated and reliable AOQS - naturally also according to special customer requirements. Corresponding RF drivers are also available.
