Operation of the first supersonic combustor-driven purely chemical CO laser is reported. The combustor is fueled with NF/sub 3/-CH/sub 4/-H/sub 2/-CS/sub 2/ and produces a mixture of HF, N/sub 2/, CS, CS/sub 2/, and S which is mixed with dry air and N/sub 2/O during a supersonic expansion into the laser cavity. A chain reaction involving CS and O/sub 2/ is initiated by the S atoms and produces CO with a non-Boltzmann vibrational-rotational energy-level population distribution. The laser produces 450 W of closed-cavity power as determined by mirror calorimetry.
