✦ Synopsis

Non-perturbative time-dependent calculations of single
and double ionization of a one-dimensional model of atomic calcium
by short and intense laser pulses were performed at various
wavelengths. The comparison of the probabilities calculated within
a two-active electron (TAE) approach with those obtained using a
single-active electron (SAE) approximation clearly demonstrates
the crucial role played by the electronic correlation and by
doubly excited states within this model, even for the formation of
Ca^+^.
