Abstract: A gyrolaser comprises: a ring-shaped optical cavity and a gaseous medium, and at least three electrodes in contact with the gas of the amplification medium, the electrodes generating charges when ignition voltage is applied; the cavity and distribution of the electrodes comprising at least one plane of symmetry perpendicular to the plane of the cavity and passing through the electrode of first type; at least one conductive ignition element set at a predetermined potential, the shape and arrangement being such that symmetry is maintained; the electrically conductive element generating an electric field locally for guiding the charges so they are distributed symmetrically in a first flow and second flow in the first and second discharge areas respectively when the ignition voltage is applied, in such a way that a first plasma and a second plasma are initiated simultaneously, respectively, in the first discharge area and in the second discharge area.
