Abstract:

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 ClO2. Mass spectrometric and absorption spectroscopic measurements of species concentrations in the NOClO2 reaction system showed that the effectiveness of production of the branched chain decreased with increasing total pressure.
