A chemical laser cavity fuel injection system is provided in which a conving-diverging nozzle for injecting an oxidizer has manifolds mounted at opposite sides and at the exit plane of the converging-diverging nozzle with fuel injection wedges connected to the manifolds and having ports therein for injecting fuel therethrough with each wedge terminating at one side of the nozzle before crossing the boundary layer region at this side of the converging-diverging nozzle to provide secondary wedges that are staggered to provide for more uniform mixing and therefore less degrading in the laser output power over prior art arrangements.

Advanced chemical laser cavity fuel injection system

A minimum length diffuser for transforming low pressure, supersonic laser haust gas flow to a subsonic flow at an elevated static pressure using structures which produce a single, near normal shock, or a single pair of normal shocks due to flow symmetry and also incorporating structures which induce a strong, stable cellular subsonic flow to allow rapid diffusion of the subsonic flow.
