The interaction between the beryllium atom and short laser fields is treated on the basis of the nonrelativistic time-dependent Schroedinger equation. We calculate total cross sections and electron energy distributions for the double ionization of the valence electrons through one- and two-photon absorption. We introduce a model potential to represent the 1s{sup 2} core. The emphasis is put on the double ionization of the valence electrons in the context of ultrashort pulses. Results will be also presented for the ionization of the inner electrons.
