Germanium Acousto-Optic Modulator (CO2 Modulator ) AOMO 80Mz GE 2.8um
AOMO 80MHz Ge 2.8μm is a compact mid-infrared acousto-optic modulator using a germanium acousto-optic medium. Designed for efficient beam control in mid-infrared laser systems, it provides stable optical switching, beam modulation and reliable system integration. Low insertion loss, high switching contrast and excellent infrared beam interaction meet optical-transmission efficiency, modulation-stability and long-term reliability requirements in mid-infrared laser applications. The favorable mid-infrared acousto-optic properties of germanium allow AOMO 80MHz Ge 2.8μm to provide efficient beam modulation for specialized laser systems operating beyond the visible and near-infrared ranges. Compact construction, a conduction-cooled base and an SMA RF interface simplify thermal management and electrical integration, making it more suitable than water-cooled designs for space-constrained optical platforms. Applications include mid-infrared optical test platforms, infrared sensing systems, laboratory photonics equipment, research laser systems and OEM optical instruments, providing low-loss, highly stable beam modulation and control for mid-infrared laser applications.
