ABSTRACT:
The invention concerns a gaseous flux laser device. To enable the removal into the atmosphere of the exhaust gases of an N.sub.2 -CO.sub.2 laser while maintaining a sufficiently low pressure in the zone where the stimulated light emission occurs, the carbon dioxide is injected through supersonic nozzles and an exhaust tube having a sufficient length is used. Application to the generating of powerful coherent light beams.
