Calculations of high-order harmonic-generation processes in xenon at 1064 nm
We perform detailed calculations of harmonic conversion in a 15-Torr jet of xenon into which a 1064-nm-wavelength 36-ps-pulse-width laser has been tightly focused, so that the peak intensity ranges from 5×1012 to 5×1013 W cm-2. The single-atom emission rates are obtained by integrating the time-dependent Schrödinger equation. We employ an improved atomic model which includes excitation and ionizat
