The present invention provides a ring laser gyro which utilizes a gas impervious block containing at least three tunnels which meet to form a closed-loop, gas containing, cavity, and allow passage of laser beams therethrough. A pair of electrodes are positioned in alignment with one of the tunnels, and positioned relative to each other to support a current through the gas and establish a glow discharge region within a portion of one of the tunnels to induce a pair of counter-propogating laser beams to propogate through the established glow discharge region in a direction transverse to the direction of the discharge current.
