We calculate the energy spectrum of electrons ejected from a model two-electron atom exposed to an intense laser pulse and follow the spectrum’s evolution in time. For the case of 13-photon double ionization, we see the appearance of above-threshold ionization peaks soon after the laser pulse reaches maximum intensity.
