Geostationary 2-Watt Laser Delivers 1Gbps Ground Link, Outpaces Starlink

Chinese researchers demonstrated a 1 Gbps optical downlink from a geostationary satellite about 36,000 km away using a 2-watt laser and a ground receiver built to correct atmospheric distortion, achieving higher speeds than Starlink and showing how adaptive optics plus multi-plane light conversion can recover usable data through turbulence.
