Abstract

Abstract: We present a theoretical study of high-order harmonic generation (HHG) driven byultrashort optical pulses with different kind of chirps. The goal of the present work isto perform a detailed study to clarify the relevant parameters in the chirped pulses toachieve a noticeable cut-off extensions in HHG. These chirped pulses are generated usingboth linear and nonlinear dispersive media. The description of the physical mechanismsorigin responsible for this extension is, however, not usually reported with enough detailin the literature. The study of the behaviour of the harmonic cut-off with this kind ofpulses is carried out in the classical context, by the integration of the Newton-Lorentzequation complemented with the quantum approach, based on the integration of the timedependent Schrödinger equation in full dimensions (TDSE-3D).
