Abstract

A curvature-wavefront-based AO system for operation with a laser guide star is in commissioning phase at Subaru Telescope. The AO system has been offered for astronomers since September 2008 using a natural guide star. This paper introduces briefly the laser system for generating a laser guide star and reports the characteristics of laser guide star on sky. The total equivalent magnitude of the laser guide star is estimated to be 10.7 magnitude. The angular size of laser guide star is around 2 arc second FWHM under a seeing condition of 1 arc second in K-band.
