We focus on the system aspects related to optics. The instrument will be a novel facility to perform strategic LGS-AO technology R&D in future years, demonstrating a 50+ W CW 589nm laser, uplink laser beam pre-compensation on sodium LGS in pulsed laser operation. The rationale for the LGS-AO facility is to have a synergy between astronomical and space awareness adaptive optics, to perform experiments related to LGS-AO technologies for astrophysics and optical communication with satellites (Optical Feeder Links), including daytime LGS-AO, for future OGS systems.enPublisher Copyright: © 2021 ESA and CNESAdaptive OpticsLaser Guide StarsOptical Communications202110.1117/12.259923385116066861
