In recent years, optical breakdown is being studied for solving of body drag decreasing in supersonic flows (see, for example, [1]). At the same time the focusing of the laser radiation can be used as a method for combustible gas ignition. Now such research is being fulfilled, as a rule, for low velocity flows (see, for example, [2]). There are some problems, which need consideration of laser-based gas ignition of supersonic flows. Numerical investigations show the reality of a stationary detonative combustion of hydrogen-air mixtures coming into the axisymmetric Laval nozzle with a high supersonic velocity ([3]).
