Abstract

We have developed and applied a model of energy transfer to noble gas atoms due to a resonance mechanism within a continuum of plasmon oscillation induced by intense laser pulses. The model is based on a generalization to 3D of the 1D many-body RPA method of Tomonaga. Total cross sections for laser energy absorption, the saturation intensities for ionization, mean energy transfer and degree of ionization of several noble gases, Xe, Kr, Ar, Ne are obtained for λ = 193 nm and λ = 1064 nm for a short Gaussian laser pulse. Probability distribution of absorption of a given number of photons in Xe is also obtained for λ = 193 nm andI0 = 1014W/cm2. The results are consistent with the rapid energy transfer necessary for multiple ionization at these frequencies.
