A purely chemical HCl laser employing transverse flow was operated with a maximum multiline output power of 13 W, which represents a chemical efficiency of 8.6% based on the total exothermicity of the pumping reaction. The required nonequilibrium concentration on Cl atoms was generated by the branched-chain reaction of NO with ClO/sub 2/. Mass spectrometric and absorption spectroscopic measurements of species concentrations in the NO/ClO/sub 2/ reaction system showed that the effectiveness of production of the branched chain decreased with increasing total pressure.
