Abstract

Pump-probe processes in the femtosecond domain with a probe VUV and dressing optical pulses are considered: ionization of the Li atom with the continuum coupled to the excited 3d state and ionization of the He atom with the coupled flat continua. In the first case, spectra and angular distributions of the photoelectrons were calcu­lated and analyzed for two linearly polarized collinear fields by numerical solution of the non-stationary Schrodinger equation. The spectrum and the angular distribu­tions are controlled by the time delay between the pulses and the two-photon detun­ing. In the second case, we concentrated on the modulation of the He ionization sig­nal as function of the angle between the field polarization vectors. Within the second order time-dependent perturbation theory for the Gaussian field envelopes, a partly analytical solution was found and used.
