Abstract : A ring laser angular rotation sensor is being designed for 100g centrifuge operation. Mode stabilization and control studies are aimed at improving the rotational sensitivity of the ring. Information on mode stability and number of simultaneously oscillating modes was being investigated through the use of an analyzing Fabry-Perot cavity. Work on mode pulling and locking, including computer results, is included. The primary emphasis of the program is on designing, evaluating, and delivery ring laser systems for the Holloman 100g, 260-inch centrifuge. Considerations include thermal and mechanical stability.
