HARMONIC GENERATION BY AN ELLIPLTICALLY POLARIZED FIELD. APPLICATION TO TIME-DEPENDENT. EFFECTIVE RANGE THEORY
Based on the time-dependent effective range theory (TDER), we develop the theory of high harmonic generation (HHG) in a strong elliptically polarized laser field. Analytical expressions for HHG amplitude were obtained in the framework of TDER and strong field approximation was introduced for degenerate initial states. Both HHG spectra and polarization properties of harmonics were calculated for negative ions H <sup>-</sup> and F <sup>-</sup> The accuracy of SFA for HHG in an elliptically polarized field was shown.
