JQA-440-W -Water-Cooled Blue Laser
The JQA-440-W is a water-cooled, LD-pumped all-solid-state Q-switched blue laser operating at 440 nm. Designed for precision industrial processing and scientific applications, this system delivers high peak power, stable output, and reliable long-term performance. Operating in Acousto-Optic Q-switched mode, the laser provides short pulse duration (~100 ns at 10 kHz & 2 W) and high repetition rate performance. The repetition rate can be customized beyond the standard 10 kHz to match specific application requirements.
