The Giant Magellan Telescope adaptive optics system will be an integral part of the
telescope, providing laser guide star generation, wavefront sensing, and wavefront
correction to most of the currently envisioned instruments. The system will provide
three observing modes: Natural Guidestar AO, Laser Tomographic AO, and Ground Layer
AO. All three modes will use the telescope’s segmented adaptive secondary mirror to
deliver a corrected beam directly to the instrument foci. We will describe the system
requirements, overall architecture, and innovative solutions found to the challenges
presentedby high-order AO on a segmented extremely large telescope. The GMT AO system
is currently in the preliminary design phase, and is expected to see first light
in 2020.
