ABSTRACT:
A ring laser gyroscope in which RF excitation is used to cause gas discharge as opposed to DC excitation which is used in conventional ring laser gyroscopes. External surfaces of the body of the ring laser gyroscope are metallized to form electrodes and an RF signal is capacitively coupled to gas reservoirs forming part of the lasing cavities.
