Description
The GTC Adaptive Optics (GTCAO) system will provide diffraction-limited capabilities in the near infrared to the GTC telescope. At first, it will use a Natural Guide Star (NGS) as a reference source, and later it will be upgraded to a Sodium Laser Guide Star (LGS), which will significantly increase the sky coverage. The GTCAO system is expected to provide a strehl ratio of 0.65 in the K-band with a bright NGS and a minimum strehl ratio of 0.1 with the LGS using a tip-tilt star brighter than 18 mag. We will review the current status of the performance tests of the GTCAO system in the IAC laboratory, and present the development of the LGS system at the IAC, which is currently in the detailed design phase.
