Paper Abstract

We measured the Rayleigh scattered light from the laser beam launched from Keck II telescope. The illumination at the pupil of Subaru telescope was recorded using the APDs of the Subaru AO system wavefront sensor. Since the field of view of our wavefront sensor is only 5 arcsec in diameter, it was possible to follow the laser beam as it travels across the telescope pupil. The maximum surface brightness of the laser beam is estimated at 16.2 mag/arcsec2.
