Abstract: A nozzle/baffle array for use within the gain generator of a cylindrical laser. The nozzle/baffle array is made of a nozzle assembly and a plurality of baffles. The baffles extend in the radial direction from the centerbody of the cylindrical laser supporting the nozzle assembly circumferentially about the centerbody. As a consequence of the novel arrangement and design of the baffles, the baffles provide a spring support for the nozzle assembly while simulataneously supporting the nozzle assembly in great alignment accuracy permitting adequate thermal growth to take place between the nozzle assembly and the centerbody of the laser.

Abstract: A method of fabricating nozzle blades for lasers in which the blade core is formed from an annular-shaped, rigid, chemically resistant material having a pair of opposed circular grooves machined therein. An open-ended exit nozzle is formed in the outer diameter of the core. The coolant channels, injection manifolds and trip manifolds are formed by electrodepositing a chemically resistant material around the core after the core has a plurality of cutouts formed therein. Final nozzle blade configuration takes place after the electrodepositing operation is completed.

Abstract: A high power floating head laser mirror assembly having a mirror head, a base structure and a plurality of flexure elements interposed between the mirror head and the base structure for "floatingly" supporting the mirror head with respect to the base structure. In order to preserve proper mirror head alignment and yet allow radial expansion of the mirror head a plurality of posts are located adjacent the flexure elements thereby exposing only a predetermined portion of the flexure element. As a result of the above assembly, the mirror surface is capable of reliable operation within a laser having a light intensity in excess of 5 Kw/cm.sup.2.
