Abstract
A high-power flowing-gas laser comprises an outer housing, an optical system including a laser channel within the housing, an impeller driven by a motor for producing a flow of gas through the laser channel, and an independent mounting for mounting the optical system to the support idependently of the housing mounting such as to isolate the optical system from the vibrational disturbances of the impeller and its motor drive. The laser channel is folded so as to be constituted of a plurality of laser channel legs disposed in a polygon configuration, there being a gas flow channel for each laser channel leg and a conduit arrangement directing the gas to flow transversely across the legs radially inwardly from the outer region of the polygon to a common collection region within the polygon. A first heat-exchanger is provided between the common collection region and the impeller for cooling the gas, and a second heat-exchanger is provided in a fixed annular array of turning vanes between the outlet end of the impeller and the inlet ends of the gas flow channels for further cooling the gas.
