Abstract : Dual waveguide lasers which are transversely excited in parallel from a common source of radio frequency are provided with one or more channels or bores connecting the laser cavities. The dimensions and configuration of the connecting channels are chosen so that the electric field from the applied RF excitation source will be higher in the connecting channels than in either of the paralleled waveguide gas discharge cavities, or that the electron collision loss to the nearby ceramic and metallic walls will be lower in the connecting channels than in the aforementioned waveguide cavities. The initial gas breakdown is thus made to preferentially occur in the connecting channels and thus force initiation of both laser cavities simultaneously. (Author).
