In order to improve a gasdynamic CO laser, comprising an excitation region, in which a laser gas is excited, a supersonic nozzle, through which the laser gas flows, a laser-active region penetrated by a resonator beam path and a closed laser gas circuit, in which the laser gas is cyclically conducted, such that this requires smaller pumping capacities and is therefore suitable for commercial uses, it is suggested that the supersonic nozzle be designed such that at a downstream outlet thereof the laser gas has a temperature in the region of approximately 80 to approximately 180 Kelvin.
