A ring laser gyroscope comprising: a ring laser gyroscope block comprising an optical cavity filled with a gain medium, the optical cavity having at least three legs that form an optical path; a radio frequency coupler positioned along the optical path, wherein the radio frequency coupler is configured to transmit radio frequency energy which causes two counter-propagating laser beams to form from the gain medium, the laser beams propagating around the optical cavity through the optical path formed by the at least three legs of the optical cavity; a gas flow bypass configured to connect at least one of the at least three legs to at least one other leg of the at least three legs.
