Abstract
A ring laser gyroscope comprises a block defining a hermetically sealed cavity for a ring laser formed when a lasing medium disposed within the cavity is excited. A cathode and an anode are attached to the block at two fill positions comprised within the cavity, and exposed to the lasing medium such that the lasing medium is ionized when a high voltage pulse is supplied across cathode and anode. At least two RF electrodes are attached to the block, positioned on opposing sides to generate a capacitive discharge for the purpose of keeping the lasing medium excited. The gyro comprises a matching circuit to tune the frequency of a radio frequency (RF) signal generated by a RF power source before the RF signal is sent to the electrodes. The matching circuit is coupled to the RF electrodes via respective lead wires, and comprises an element matching network.
