ABSTRACT:
A folded longitudinal flow CO.sub.2 laser with an output of at least several hundred Watts, having a rectilinear tube device of dielectric material containing CO.sub.2, comprising a plurality of individual tubes between end flange devices, disposed serially per fold path. At least one intermediate flange device supports the individual tubes and is aligned with the end flange devices. The intermediate flange device has a gas connecting aperture and a cavity aligned with the individual tubes and the gas connecting aperture, and there is a gas tight sealing device between the intermediate flange device and the individual tubes. A supporting device, which is flexurally-resistant, extends parallel to the longitudinal axis of the laser and has two end zones which are rigidly fixed in the end flange devices in a flexurally-resistant fashion and without clearance. The intermediate flange device is carried by the supporting device in such a manner that it is moveable lengthwise relative to the supporting device to the extent required by heat expansion. And, the individual tubes are supported in such a manner that the are moveable relative to said end flange devices and said intermediate flange device to the extent required by heat expansion.
