From UV solid-state lasers to CO? laser systems, modern laser applications require Q-switches capable of delivering fast switching, stable pulse generation, and reliable operation under high optical power. CASTECH Acousto-Optic Q-Switches are engineered to meet these requirements with broad wavelength coverage, high damage threshold, and excellent modulation performance for demanding laser systems.

Supporting operating wavelengths from 310 nm to 10.6 μm, the AO Q-switch series provides single-pass transmittance up to 99.6%, modulation loss exceeding 85%, and a damage threshold greater than 1.0 GW/cm². Multiple aperture sizes, operating frequencies, and crystal materials allow engineers to optimize laser performance across a wide range of laser platforms and operating conditions.

Designed for laser marking, medical laser equipment, material processing, and scientific research, CASTECH AO Q-switches provide stable pulse control and reliable long-term operation for precision laser applications.
