Abstract: A ring laser gyroscope comprises a laser block that includes a resonant internal cavity defined by a plurality of surfaces of an optical closed loop pathway, and a plurality of electrodes coupled to the laser block. The electrodes are configured to generate a pair of counter-propagating laser beams from a lasing gas in the optical closed loop pathway. The ring laser gyroscope also includes a field reducer shield comprising an electrically conductive material, with the field reducer shield located completely within the laser block. The field reducer shield is configured to modify an electric field generated by the plurality of electrodes to substantially prevent ions in the laser block from migrating toward the plurality of surfaces of the optical closed loop pathway.

Abstract: A partially-insulated cathode for exciting plasma in a plasma chamber is provided. The partially-insulated cathode includes a conductive structure enclosing a cavity having a cavity surface and an insulating material contiguously covering a portion of the cavity surface from the cavity opening up to an insulation height that is less than a cavity height. Cross-sections of the cavity in X-Y planes have at least one respective cavity-width. A cavity opening has a diameter less than a minimum cavity-width of the at least one cavity-width.

Abstract: A ring laser gyroscope configured to reduce alignment shifts in at least one critical alignment of the ring laser gyroscope is provided. The ring laser gyroscope includes reflective components configured to direct clockwise optical beams and counter-clockwise optical beams in at least one lasing plane; at least one ring-laser-gyro mounting feature having at least one respective through hole; and at least one minimally-threaded screw positioned in the at least one respective through hole. An unthreaded section of the minimally-threaded screw is contactlessly encased in the at least one respective through hole. A threaded-end of the at least one minimally-threaded screw is threaded in a respective at least one threaded hole in a gyro frame, the gyro frame spanning a reference mounting plane.
