According to Scot Olivier, project scientist for the adaptive optics subsystem, the Shane is the first major astronomical telescope with such a laser Laser guide stars are small bright spots in the sky, generated with laser beams for use in astronomy with adaptive optics imaging. They allow one to substantially mitigate disturbing atmospheric effects. Adaptive optics and lasers are giving ground-based telescopes better-than-Hubble views. The system—using lasers, deformable mirrors, and supercomputers—is enabling some ground telescopes to get better images than the Hubble Space Telescope. Today, laser guide stars are an A laser guide star is an artificial star image created for use in astronomical adaptive optics systems, which are employed in large telescopes in order to correct atmospheric distortion of light (called astronomical seeing). Adaptive optics (AO) systems require a wavefront reference source of light called a guide star. Natural Adaptive optics allows the theoretical limit of angular resolution to be achieved from a large telescope, despite the presence of turbulence. Thus an eight meter class telescope, such as one of the four in the Very Large Telescope operated by ESO in Chile, will in future be routinely capable of an angular resolution of almost 13 Jul 2016 Laser Guide Star Adaptive Optics. The Keck laser guide star (LGS) adaptive optics (AO) systems are available for science with NIRC2 and NIRSPAO on Keck II and with OSIRIS on Keck I.

Please follow the links below to learn more about laser guide The Keck Observatory began science observations with a laser guide star adaptive optics system, the first such system on an 8–10 m class telescope, in late 2004. This new capability greatly extends the scientific potential of the Keck II Telescope, allowing near–diffraction?limited observations in the near?infrared using The Keck II Telescope is the first 8–10 m class telescope equipped with a laser guide star adaptive optics (LGS AO) system. Under normal seeing conditions, the LGS AO system produces K?band Strehl ratios between 30% and 40% using bright tip?tilt guide stars, and it works well with tip?tilt guide stars as faint as mR = 18, 13 Jul 2016 Astronomical observations using natural guide star (NGS) adaptive optics are limited to areas of the sky within ~30 arcseconds of a fairly bright star (R<13.5 using the Keck system). This leaves 99% of the sky beyond the reach of AO. The W. M. Keck Observatory provides a sodium (Na) laser guide star on 30 May 2013 A second development followed by the group in collaboration with industry is fiber relays using Photonic Crystal Fibers. Such$
