Water-Cooled Acousto-Optic Q Switch I-QS027-3C4G-Q5-ST1
The I-QS027-3C4G-Q5-ST1 water-cooled fused-silica acousto-optic Q-switch is designed for high-power lamp-pumped or diode-pumped Nd:YAG lasers. It operates at 1064 nm and 27.12 MHz with a 3 mm clear aperture, providing stable, reliable Q-switching control for high-power pulsed laser systems. High-quality fused-silica crystal, precision optical processing, and high-performance antireflection coatings developed by G&H are combined with advanced acoustic-management design and optomechanical optimization to provide excellent thermal management under high-power operation while maintaining outstanding beam quality and high optical transmission. G&H's patented 'Muma' manufacturing process significantly improves corrosion resistance while ensuring excellent RF power handling and long-term operating stability, particularly for industrial laser processing and research lasers. Model identification: I-QS027-3C4G-Q5-ST1 (200306-0101/01).
