Paper Abstract

Experimental results have demonstrated very high order harmonic generation in rare gases exposed to intense laser fields. We use time-dependent methods to calculate the single atom emission spectrum in a number of systems. These spectra show many of the same features seen experimentally, e.g. a broad plateau that depends in intensity and extent on the ionization potential. To explain the observed spectra, we fold these single atom results into a full solution of the propagation equations for the nonlinear medium. This leads to impressive agreement between theory and the experiment for xenon, both in the absolute number of photons observed as well as the intensity dependence of all harmonics through the 21st. The use of time-dependent methods also facilitates a comparison between photon and electron emission processes.
