Abstract

In a gas transport laser with axial gas flow, a radial blower is provided for the gas circulation on the axis of which a laser resonator has been arranged. The laser resonator is concentrically enclosed by a ring channel serving as a cooling section. For this purpose, several heat exchangers are provided in the ring channel which are connected to a water reservoir. The water reservoir preferably serves as the cover plate of the radial turbine, and carries--at the same time--the cathode being shaped as a ring electrode.
