  • Slab-waveguide CO.sub.2 laser
    Patent number: 5412681
    Abstract: An improved slab-waveguide CO.sub.2 laser which includes two parallel, rectangular, flat, spaced-apart, slab electrodes whose surfaces excite a laser gas and guide laser light in a plane perpendicular to the surfaces of the slab electrodes. The component of the light propagating parallel to the electrode surfaces is not guided and is acted on only by resonator mirrors which form an unstable resonator. The improved slab-waveguide CO.sub.2 laser operates on a single vibrational transition of the CO.sub.2 molecule by employing wavelength selective optics.
