Abstract

The spectrum of scattered radiation was computed for an electron, bound initially in the 2s-state of a hydrogen atom, and driven resonantly by the sinusoidal field of a moderately intense linearly polarized laser. A numerical solution of the time-dependent Schrodinger was performed for the duration of a several femtosecond laser pulse. The radiation which emerged from this transient state was characterized by the spectrum of the autocorrelation function of the electronic acceleration. Copious radiation, near the second harmonic, was emitted prior to ionization.
