A generalized kinetic model of atomic level populations.in an optically dens. plas.a excited by las.r puls.s.of arbitrary duration is.formulated and *** model is.bas.d on a nons.ationary expres.ion for the probability of excitation of an atomic trans.tion and takes.into account the effects.of las.r puls. penetration into an optically dens. medium.A univers.l formula for the excitation probability as.a function of time and propagation length is.derived and applied to the cas. of a Lorentzian s.ectral profile of an atomic trans.tion excited by a las.r puls. with a Gaus.ian *** features.of nons.ationary excitation probabilities.are pres.nted for different optical depths.of the plas.a,las.r puls. durations.and carrier *** formulas.derived here will be us.ful for the des.ription of atomic populations.excited by las.r puls.s.under realis.ic conditions.of dens. plas.as.
