Résumé : We have solved the time-dependent Schrödinger equation for a hydrogen atom, initially in its ground state, subject to a strong, ultrashort laser pulse of high frequency, ω=2.0 a.u. We compare and interpret our results in terms of the time-independent Floquet eigenvalues. Even for an ultrashort pulse of 3 cycles half-width, the Floquet adiabatic picture is a very good approximation. We discuss the physical reasons and also the visible deviations from the single-resonance-state approximation. © 1995 The American Physical Society.
