Minimum Length Diffuser for Chemical Lasers.

Abstract

The invention concerns a minimum length diffuser for transforming low pressure, supersonic laser exhaust 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.
