High-order harmonic generation: A quantum-mechanical description and the effects of propagation

A theoretical investigation of the generation of high-order harmonics in an ensemble of atoms interacting with femtosecond laser pulses of high intensity is conducted. It is shown that the cut-off frequency of the photoemission spectra is saturated in a laser field of subatomic strength. A model of...

Zusammenfassung:	A theoretical investigation of the generation of high-order harmonics in an ensemble of atoms interacting with femtosecond laser pulses of high intensity is conducted. It is shown that the cut-off frequency of the photoemission spectra is saturated in a laser field of subatomic strength. A model of the effect dispersion has on the radiation of high-order harmonics in extended environments is proposed.
