Abstract

In order to improve a gasdynamic CO laser comprising a gas supply means supplying a laser gas, an excitation region, in which the laser gas is excited, a supersonic nozzle arranged downstream of the excitation region and having the laser gas flowing therethrough and a laser-active region which is penetrated by a resonator beam path, such that it is possible to excite the laser gas in a more optimum manner, it is suggested that the laser gas be excited in the excitation region by means of a high-frequency discharge in a high-frequency discharge region and that the high-frequency discharge region end in front of the supersonic nozzle.
