Acousto-optic Q-switching (AOQS) is a laser that works in the laser cavity and generates short pulse peak power by actively adjusting the Q value in the laser cavity. AOQS is usually the loss of modulating level 0 light. When the RF driver of AOQS is turned on, the laser in the cavity cannot form oscillation due to the diffraction of the level 0 light, the cavity loss increases and prevents the laser output. When the RF driver is turned off briefly, the accumulated optical power in the laser cavity is emitted in the form of a pulse to generate a pulsed laser, and the process can be repeated at a rate of more than 100kHz. AOQS can operate either in the Bragg state with only a single diffracted beam like AOM(acousto-optic modulator), or in the Raman-Nath state with multiple diffracted beams.

Goptica has a complete range of polarization-oriented (cut) or unpolarized laser solutions that can be adapted to include lamp-pumped lasers, as well as LD-pumped lasers. Goptica AOQS products range in wavelength from ultraviolet to far infrared, with diameters up to 12mm. AOQS selects high-quality acousto-optic materials (fused quartz, quartz crystal, Ge crystal, etc.), which can be designed into shear and longitudinal wave modes according to needs. The process uses high-quality optical polishing, anti-reflective coatings with low reflection and high damage, reliable welding technology, and novel acoustic management and opto-mechanical design technology to achieve excellent thermal management and maintain excellent beam quality and high transmittance.

Goptica can provide a series of AOQS matching RF drivers, which can be selected according to the product specification.
