摘要：

We have solved the time-dependent Schrodinger equation for a hydrogen atom, initially in its ground state, subject to a strong, ultrashort laser pulse of high frequency, omega = 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.
