We report our computational studies concerning the response of a hydrogen atom initially in its ground state subject to short
intense laser pulses with linear polarization. The time-dependent Schrdinger equation in a space-translated Kramers-Henneberger
frame of reference is integrated numerically on a parallel computer with virtual shared memory (KSR1-32). The singularities
of the system's Hamiltonian in cylindrical coordinates are eliminated by expanding the wave function in a Bessel-Fourier series.
In order to reduce storage requirements a discrete variable representation of the grid points is employed, which diagonalizes
the potential matrix. The implemented unitary split operator algorithm guarantees an exact and efficient propagation in time.
After the atom's interaction with the laser pulse the electronic energy distribution as well as the spectrum of the emitted
photons are calculated from the final wave function.
