Abstract

Summary form only given. An atom interacting with high-intense laser pulse in the dynamic stabilization regime provides a long-lived source of high-order harmonics emitted in the form of long trains of attosecond pulses. The peculiarities of electron localization dynamics cause a number of unusual properties of harmonic generation process in this regime among which are an increase of pulse train envelope despite ionization and the possibility of high-order harmonic production with arbitrary laser polarizations including circular one. These unusual features can be used as a probe of this special regime of strong-field laser-atom interactions.
