Abstract: A high energy laser mirror-heat exchanger is described which comprises a faceplate supporting a mirrored surface, a manifold plate adjacent the faceplate and defining a plurality of passageways for distributing fluid coolant to the adjacent faceplate surface, a heat exchanger adjacent the manifold plate having a plurality of wall members configured in a isogrid configuration which may define a plurality of triangularly shaped passageways therebetween for conducting coolant to the manifold plate the intersections of said wall members defining a plurality of insulated passageways for conducting coolant away from said manifold plate, and a backing plate attached to the heat exchanger including coolant inlet and outlet means.

Abstract: A chemical laser nozzle blade support system which incorporates therein at least two continuous flexure member to secure the nozzle blades of the laser to the laser body. The blade and flexure member are formed with a radius, R, and each side of the member is supported by a surface having a radius, R.sub.1. Under nonstress conditions the blade and member are subjected to the same pressure and have the same radius of curvature. During operation of the laser, axial deflections occur which cause the blade end of the member to deflect in a radial manner which induces bending in the member. The magnitude of the bending stress is limited by establishing the value of R.sub.1 such that the change in radius of curvature cannot exceed a desired value. The resulting blade load is therefore primarily in tension with the only bending being that induced by the structural deflection.
