Abstract

Sodium laser guide stars have been proposed1,2 as a means to correct for the effects of atmospheric turbulence in large astronomical telescopes. Several groups3-6 have produced such guide stars, but as yet, none has been able to close a control loop for an adaptive optics system using this means largely because of the limited power available in the laser system. In this paper, the effort to utilize a high power laser system developed by LLNL for laser isotope separation, for the generation of a sodium guide star, is described.
