Analytic formulas describing high-order-harmonic generation (HHG) by atoms in an intense
laser field with small ellipticity are obtained quantum mechanically in the tunneling limit. The
results show that factorization of the HHG yield in terms of an electron wave packet and the
photorecombination cross section (PRCS) is valid only for s states of a bound atomic
electron, whereas the HHG yield for p states involves two different atomic parameters. For
the latter case, elliptic HHG spectroscopy enables one to retrieve both the energy and …

Analytic formulas describing high-order-harmonic generation (HHG) by atoms in an intense laser field with small ellipticity are obtained quantum mechanically in the tunneling limit. The results show that factorization of the HHG yield in terms of an electron wave packet and the photorecombination cross section (PRCS) is valid only for states of a bound atomic electron, whereas the HHG yield for states involves two different atomic parameters. For the latter case, elliptic HHG spectroscopy enables one to retrieve both the energy and angular dependence of the PRCS of the target atom, as we illustrate for the case of HHG by Xe in a midinfrared laser field.
