Abstract

The resonator of a gas dynamic laser, particularly, of a high power gas dynamic laser, is mechanically decoupled from the other components of the laser by a pair of elastic restoring ring membranes and stay bolts. The flow channel of the laser is mechanically connected through the ring membranes to the resonator. A pair of tubular, elastic sleeve membranes seal the flow channel in a vacuum tight manner. The laser beam decoupling elements are secured to bushings extending coaxially through said elastic tubular sleeve membranes. The restoring forces of the ring membranes are large relative to the differential force resulting from said tubular sleeve sealing membranes.
