Abstract : The patent describes how ring laser beam locking is substantially eliminated by inserting an optical retardation plate into the circulating laser beams. The retardation plate is positioned with its optical axis perpendicular to the laser beams and is located at a point of minimum distance from the ring laser center of rotation. Further laser beam decoupling is achieved by mechanically vibrating the retardation plate.
