The combustion kinetics of H-2-air mixtures containing small amounts (< 1%) of ozone is analyzed for the case of excitation of asymmetric vibrations Of 03 molecules by CO2 laser radiation with a wavelength of approximate to 9.7 mu m. It is shown that the irradiation leads to acceleration of the collisional dissociation of O-3 molecules, activation of the chain ignition mechanism, and a decrease in the induction period and ignition temperature. The excitation of asymmetric vibrations of O-3 molecules by the CO2 laser radiation is 10-10(3) times more effective than the currently used method of combustion initiation based on local heating of a medium by IR radiation.
