Abstract
In a laser system activated by a molecular gas there is provided a novel nozzle construction for the purpose of effecting expansion of the gas in a minimum period of time but without destroying laminar flow conditions therein. Instead of the relatively long single nozzle of the prior art there is provided a plurality of nozzles expanding in three dimensional directions and arranged in parallel aligned relationship in a cluster closely adjacent each other. The nozzles may be of many cross-sectional shapes but in one embodiment the walls are concave, such that a relatively large wall angle with respect to the direction of flow at the throat of the nozzle diminishes progressively toward the end of the nozzle so that at such end the nozzle walls will be substantially parallel with each other, whereby to discharge the gas stream therefrom in a jet of constant cross-sectional area.
