The Keck laser guide star (LGS) adaptive optics (AO) system is available for science with NIRC2, OSIRIS, and NIRSPAO and has been quite a productive instrument so far (see refereed or all science papers).
Please follow the links below to learn more about laser guide star adaptive optics, the design and performance of the Keck system, and planning science observations.
