Primary reactants in nonstoichiometric proportions interact chemically in a reaction chamber to produce a high temperature, high pressure gas containing a substantial percentage of free atoms. Aerodynamic expansion of the gas effluent from the reaction chamber preserves the free atoms in an unrecombined condition. A secondary reactant is admixed with the main gas stream after the expansion process and reacts chemically with the free atoms to produce a gas which is in a vibrational state population inversion condition and which lases in an appropriate optical cavity.
