Water-Cooled Acousto-Optic Q Switch I-QS027-4S4G-B5
The I-QS027-4S4G-B5 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 4 mm clear aperture for stable, reliable Q-switching of high-power pulsed systems. Part of G&H's classic 'industry standard' series, it uses high-quality fused silica, precision optical processing, and internally developed high-performance AR coatings for high transmission, low optical loss, and excellent laser damage threshold. It meets high-reliability and long-term stability requirements in industrial laser processing, medical lasers, and research. Model designation:I-QS027-4S4G-B5 (200307-0004/03).
