2μm Acousto-optic Q-switch Series
The acousto-optic Q switch realizes the Q switch of the 2μm laser cavity by the principle of acousto-optic interaction. High intensity pulsed light is generated by actively controlling the quality factor Q (loss) in the cavity. The use of unique acousto-optic device manufacturing and packaging technology ensures that our products are robust and compact, with stable beam quality and excellent heat dissipation performance. It is widely used in high repetition frequency Q-switched laser, laser cutting, laser engraving, and other fields.
