We study the quantum mechanical response of a model two-electron atom to a strong laser pulse over a range of frequencies centered in the vicinity of five-photon ionization. We investigate the variation of single and double ionization yields, determined at the end of the pulse, as a function of the maximum intensity of the incoming laser pulse. We suggest that several features of the ionization yield are the result of the internal structure of our model atom. © 2000 American Institute of Physics.

    We propose a cross-correlation technique for measuring ultrashort soft x-ray pulse shapes using the rapid increase in Kr[sup +] ion density caused by optical field-induced ionization, which operates as an ultrafast x-ray absorption switch. Using this technique, we measured the shape of a soft...

    The process of multi-electron tunneling in strong fields has, to the authors’ knowledge, never been considered in detail. In principle, it is one possible mechanism for multi-electron ionization in strong laser fields. We have carried out first analytical and numerical studies of this...
