Scientific paper

Sodium laser guidestars have been proposed as a means to correct for the effects of atmospheric turbulence in large astronomical telescopes. Several groups have produced such guidestars, but as yet, none have 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. The effort to utilize a high power laser system developed by LLNL for laser isotope separation, for the generation of a sodium guidestar, is described. The requirements of the laser system are developed by examining the photon signal necessary to achieve sufficient signal to noise in the wavefront detector. The laser system developed for isotope separation is described and the performance characteristics are presented. The beam transport system is discussed and the results that were generated are presented.
