ABSTRACT:
An aerodynamic window for gas lasers, has an active chamber with a beam penetration opening free of solids. An end of a beam duct is connected to the beam penetration opening and is transversely penetrated by a nozzle duct of a gas flow window through which compressed gas can flow. A beam outlet opening delivers a laser beam to an exterior space which is preferably at atmospheric pressure. A suction chamber of a differential pump is provided between the other end of the beam duct and the beam outlet opening, and the working pressure of the differential pump is approximately equal to the pressure in the other end of the beam duct on the suction chamber side.
