Abstract
A spherical jellium model and time-dependent density functional theory for two-color ultrashort laser pulses as a function of phase difference between two fields were used to calculate the above threshold ionization (ATI) spectra of small metal clusters. ATI spectra and the ionized electrons fluxes were obtained in the two opposite directions of the linearly polarized laser fields. It is found that ATI spectra has long energy plateaus, with cutoffs up to 30-40 times the ponderomotive energy Up. However, no extended plateaus were observed in high-harmonic generation spectra.
