Abstract
In order to so improve an aerodynamic window device for a laser which isolates the laser cavity pressure and comprises a jet nozzle and a diffuser arranged opposite the jet nozzle for generating a free jet extending from the jet nozzle to the diffuser and covering an exit aperture, that variable setting of the pressure level in the laser cavity is possible, it is proposed that a side wall (80) of the diffuser (72) which faces away from the laser cavity (34) be adjustable, at least in sections thereof, relative to a free jet direction (68).
