Abstract
The dependence of the high-order harmonic cutoff spectrum from the absolute phase of the laser pulse is here experimentally investigated. Noticeable shifts are observed. Their interpretation is proposed with a model based on the absolute-phase dependence of the trajectories of the photoelectrons that contribute to a given harmonic order.File in questo prodotto:
