The emergence of ultraviolet (UV) lidar systems in Earth‐observation satellites has revolutionized atmospheric sensing, enabling precise profiling of aerosols, trace gases, and cloud structures. Central to these UV lidar systems is the 397 nm Space Acousto-Optic Modulator (AOM) Series—a family of high‐performance devices engineered to meet the stringent demands of spaceborne applications. https://www.cq-smart.com/397nm-space-aom-series
