    Femtosecond laser pulse energy self-stabilization

    A photoconductive switch driving a Pockels cell ensures energy self-stabilization of ultra-fast laser pulses from single shot to hundreds of kHz. In this kind of stabilization, the pulse corrects itself. In a ...

    High order harmonic generation by non-linear reflection of a pedestal-free intense laser pulse on a plasma

    We demonstrate the influence of the prepulses and ASE of ultrashort pulses interacting with a solid target by addressing the direct comparison of the harmonic spectra generated by reflection onto a solid targe...
