KINETICAL PHENOMENA IN DENSE VAPOURS OF METALS

Abstract

The work covers the dense stationary and pulse-made vapours of metals. The aim of the worh is to investigate the processes of plasma excitation and formation, laser generation, laser radiation scattering and fluorescence in the dense vapours of metals. The characteristics of discharge in the dense vapours of copper have been analysed. The increments of developing four-wave instability of the intensive laser beams in the three-level medium and also the resonance fluoroscence spectra in the strong laser field have been modelled numerically. The generation in the dense vapours of metals has been obtained firstly, the characteristics of erosion UV-laser plasma and also the breakdown thresholds in the vapours of a namber of the metallic targets have been measured, the effects of resonance breakdown on the surface, instabilities of the laser beams in the resonance media and multicomponent fluorescence have been discovered. The investigation results can be introduced in the some research instiutesAvailable from VNTIC / VNTIC - Scientific & Technical Information Centre of RussiaSIGLERURussian Federatio
