Abstract

The present nozzle assembly for gas-dynamic high efficiency lasers with a oling system comprises a plurality of specially formed nozzle members or so-called lamellae. Each nozzle has its own cooling passages, matching bodies and glide surfaces. A series of nozzle members are placed in thermal contact with each other within a mounting or holding block. A coolant flows through said cooling passages which extend through each nozzle throat region and through matching bodies of the nozzle members so that a uniform temperature prevails across the nozzle assembly whereby the nozzle dimensions are maintained constant especially at the nozzle throat width and whereby leakage flows are eliminated.
