Adaptive Optics: Guide Stars
Scientific paper
The authors describe the design and the early results of a feasibility experiment for sodium-layer laser-guide-star adaptive optics. The laser beam is projected upward from a beam director that is located ≍5 m from a 0.5-m telescope and forms an irradiance spot ≍2 m in diameter at the atmospheric-sodium layer (at an altitude of 95 km). The authors give an overview of the experiment's design and the laser systems, describe the experimental setup, show preliminary photometric and open-loop wave-front-sensor data on the guide star, and present predictions of closed-loop adaptive-optics performance based on these experimental data. The long-term goal of this effort is to develop laser guide stars and adaptive optics for use with large astronomical telescopes.
