Abstract

We present an update on the Visible Light Laser Guidestar Experiments ViLLaGEs) taking place at the Lick Observatory. The goal of phase one of these experiments is to demonstrate the practical feasibility of using MEMS deformable mirrors in astronomical adaptive optics systems, including the use of open-loop wavefront sensing and control. The goal of phase two is to incorporate a laser guide star and demonstrate laser up-link correction, again using a MEMS deformable mirror running in open-loop. The overall set of experiments is designed to demonstrate these and various other new concepts leading to feasible and low-cost laser guidestar adaptive optics that can be used for science observing in the visible wavelength bands.
