title = "Design and predicted performance of the GMT ground-layer adaptive optics mode",
abstract = "The Giant Magellan Telescope is planning to provide adaptive wavefront correction of the low layers (<1 km) of atmospheric turbulence in support of wide-field instrumentation. This ground-layer adaptive optics (GLAO) mode will use the adaptive secondary mirrors to provide improved image quality over approximately 7 arcminutes FOV. We present a comparison between the use of a sodium laser guide star asterism plus three tip-tilt natural guide stars versus natural guide stars only on the average seeing width improvement. The layout and components of both (laser beacon based and natural star only based) GLAO concepts are described and the impact and interaction with other GMT subsystems is analyzed.",
