Abstract
The relative wander in the positions of the laser beacons in a multiple beacon system limits the accuracy to which the wavefront can be measured. We describe the design of an experiment to test methods for reducing laser beacon wander. The system employs an excimer laser producing Rayleigh guide stars at an altitude of 10 km mounted at the Coude focus of the Mt. Laguna 1 m telescope. The experimental tests are based on simultaneously creating two guide stars and measuring their apparent differential motion in a set of projection and detection schemes that includes: full aperture broadcast, partial aperture broadcast, full aperture reception, and partial aperture reception.
