ABSTRACT:
A ring laser gyroscope having a self-compensating discharge path between a single anode and cathode which comprises equal segments in the laser path in series with a channel that interconnects the laser path and allows a single current to flow within the equal segments in opposite directions with respect to the laser beam thereby cancelling the Fresnel-Fizeau drag effect. This design is applicable also to laser gyroscopes having two or more rings in a single gyro block structure.
