Laser Guide Star Adaptive Optics
In October 2006 (Keck I) and February 2007 (Keck II), the AO systems were upgraded with a new wavefront sensor and a new wavefront controller. The performance of this system has been characterized and is presented in KAON 489.
The Keck laser guide star (LGS) adaptive optics (AO) system is
available for science with NIRC2 and OSIRIS 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.
