The dynamics of expansion of gas and condensed particles under conditions of local laser heating of metal surface

A model of formation of the products of interaction between focused electromagnetic radiation and metal surface is considered. A description of the dynamics of expansion of gas cloud is given; estimates are obtained of the amount, size and velocity of scattering of condensed particles being formed. The obtained results enable one to gain a better notion of the possibilities of analysis of emission spectra for qualitative and quantitative investigation of the atomic composition of solid sample under the effect of laser radiation.
