Investigation of laser plasma for solid element composition microanalysis

Analytical characteristics LTE existence, excitation temperature, plasma plume expansion, duration of analytical spectral lines. of the plasma formed at atmospheric pressure after sharply focused laser beamrsolid surface interaction were under investigation. At the time interval of analytical interest 100–400 ns.microplasma was found under LTE conditions with excitation temperature up to 10,000 K and its volume was spatially stabilised. q1999 Elsevier Science B.V.
