Air-Cooled Acousto-Optic Q Switch I-QS041-1.8C10G-4-GH21
The air-cooled acousto-optic Q-switch I-QS041-1.8C10G-4-GH21 operates at 1064 nm and 40.68 MHz with a 1.8 mm clear aperture and conduction cooling through its base. Quartz crystal, precision optical processing, high-performance AR coatings, optimized acoustic management, and optomechanical construction maintain excellent beam quality and transmission with efficient thermal control and stable pulses. It suits end-pumped Nd:YAG and Nd:YVO₄ systems requiring stable Q-switching and good thermal management. Model identification: I-QS041-1.8C10G-4-GH21 (200504-0047/03).
