Abstract:		The experimental research of influence of focused impulsno-periodic radiation СО2 - the laser on initiation and development of process of distribution of burning in to - and a supersonic stream homogeneous fuel-air of mixes (Н2+air, СН4+air) is spent. Radiation СО2-laserа extended across a stream and was focused by a lens on an axis of a supersonic stream. The shadow scheme was applied to registration of structure of a current with a crack and the flat knife located along a stream. The image it was fixed by the high-speed chamber in due course expositions 1.5 µs and frequency of shots 1000 1/s. The structure of a zone of burning on an example of own luminescence of a flame on lengths of waves of radicals OH and СН is studied. In the spent experiments by methods of issue spectroscopy distribution of intensity of radiation a component in the field of the optical category has been investigated.
