Abstract
A ring laser is provided with at least one retroreflector external to the ring laser closed-loop path for redirecting energy extracted from one of the counterpropagating beams into the opposite traveling counterpropagating beam. The redirected energy is modulated so as to oppose the normal coupling between the counterpropagating beams which causes lock-in.
