Abstract

The interaction of powerful laser radiation with the dense plasma accompanies by development of different kind of parametric instabilities in the plasma. In the unstable plasma little indignation, up to thermal noise, increase exponentially to time, it exerts influence to macroparameters of plasma. The theory of parametrical resonance shows, that ideas of parametrical instabilities permit to understand effects of the interaction powerful radiation with the laser plasma. The great absorption of light by the laser plasma, the modulation reflection, the generating of laser radiation harmonics by plasma, the parametrical acceleration of plasma particle, the hard ionize radiation of plasma concern by number of these effects. The chemical reactions which lead to the formation of gas halo with high concentration of NO₂, 0₃ and ions oxygen take place in the air surrounding plasma center to interaction of ionize radiation. The gas halos around the plasma optical breakdown center ofthe air screen plasma radiation in the visible spectrum section.
