We consider time-evolution of atoms with one and two active electrons
in a strong pulse of IR and/or XUV fields. We use either a direct time
propagation on a numerical grid or seek basis-based solution of the
time-dependent Schroedinger equation. The final field-free state is
propagated to the detector to find energy and momentum distribution of
the photoionized electrons. Examples include multi-photon
single-electron ionization of H and Li atoms as well as two-color IR
and XUV double ionization of He.
