  • Gas laser in particular CO.sub.2 laser
    Patent number: 5400357
    Abstract: A gas laser, in particular a CO.sub.2 laser, contains as laser medium a gas that is excited into a plasma by a HF energy supply, in particular a microwave energy supply, whereas the HF waves are coupled into the laser medium (4) through a rectangular waveguide (1). In order to obtain a compact structure with an efficient coupling of the HF energy, coupling is ensured by means of a ribbon-shaped waveguide (3) that projects into the rectangular waveguide (1) and thus also allows the outcoupling on all sides of the rectangular waveguide.
