Abstract
A compact, solid state, active laser gyroscope was developed using two counter-propagating waves in a mode-locked ring laser. The sensitivity of the ring laser as a probe for non-reciprocal effects results from the fact that the difference between cavity perimeters in either direction is being probed. The beat note between the two pulse trains provides the error signal needed for stabilization. In the stabilized laser, any change in rotation of the laser support appears as an error signal in the feedback.
