ABSTRACT:
A pneumatically dithered ring laser gyroscope features providing an oscillatory motion directly to a segment of the excited gas which serves as the laser photon source. Alternately switching ionizing potential between two cathodes in appropriately designed cavities establishes desired oscillatory gas velocities to effect emitted frequencies within the gyro, thereby permitting the detection of rotational rates below the "lock-in" rate of the undithered gyro.
