Génération d'impulsions attosecondes sur miroir plasma à très haute cadence

Abstract : Focusing an intense laser pulse onto a solid surface leads to the almost complete ionisation of matter and the creation of a plasma of near-solid electronic density. Collective charge dynamic of the plasma electrons is then driven by the laser field and can give birth to a train of XUV attosecond pulses. This work aims at demonstrating that plasma dynamics can be driven with attosecond precison by the laser field in order to generate reproducible attosecond XUV pulses. Therfore we built up the first laser-solid interaction setup working at kHz repetition. The first XUV emission being detected, we demontrated the attosecond control of the plasma electron dynamic driven by a few-cycle waveform laser pulse by observing the emission spectrum. Finally, we showed the first generation of a bunch of spatially isolated attosecond pulses from plasma mirror with the attosecond lighthouse technique.
