We study the dynamics of avalanche ionization of pure helium nanodroplets activated by a weak extreme-ultraviolet (XUV) pulse and driven by an intense near-infrared (NIR) pulse. In addition to a transient enhancement of ignition of a nanoplasma at sh

Abstract Ultrafast electron dynamics drive phenomena such as photochemical reactions, catalysis, and light harvesting. To capture such dynamics in real-time, femtosecond to attosecond light sources are extensively used. However, an exact match betwee

We observe a new regime of coherent XUV radiation generation in noble gases induced by femtosecond pulses at very high intensities. This XUV emission has both a reduced divergence and spectral width as compared to high-order harmonic generation (HHG)

Publikováno v: Photoniques. :28-33

Les sources attosecondes sont maintenant une realite. Elles ont ouvert le domaine de l’attoscience et permettent l’etude de dynamiques ultrarapides a des echelles de temps attoseconde et, en particulier, l’etude de dynamiques electroniques. Ces
