    Ion acceleration in ultra-high contrast regime

    In this work, we demonstrate that the contrast of high intensity laser pulses is a key issue for many problems dealing with high-field interaction with solid-density matter. As an example, we will discuss the ...

    High-order harmonic generation from plasma mirrors

    We discuss the two mechanisms involved in high-order harmonic generation from plasma mirrors, and show that they can be clearly identified experimentally. The very different phase properties of the correspondi...

    Probing the dynamics of plasma mirrors on the attosecond time scale

    We demonstrate that the generation of high-order harmonics (HHG) of a laser on plasma mirrors preserves the coherence of the laser. We then exploit this coherence to study the dynamics of the plasma electrons.

    Coherent dynamics of plasma mirrors

    Emission coherence is crucial to the potential of future X-ray sources based on high-order harmonic generation from laser-driven plasmas. Contrary to expectations, coherent emission is possible, but only if th...

    Plasma mirrors for ultrahigh-intensity optics

    Specular reflection is one of the most fundamental processes of optics. At moderate light intensities generated by conventional light sources this process is well understood. But at those capable of being prod...

    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...

    Time-resolved analysis of the X-ray emission of femtosecond-laser-produced plasmas in the 1.5-keV range

    Recent experimental results on ion beams produced in high-intensity laser–solid interactions indicate the presence of very intense electric fields in the target. This suggests the possibility of efficiently he...

    Non-thermal melting in semiconductors measured at femtosecond resolution

    Ultrafast time-resolved optical spectroscopy has revealed new classes of physical1, chemical2 and biological3 reactions, in which directed, deterministic motions of atoms have a key role. This contrasts with the ...

    Ultrafast Plasma Studies by Phase Measurements with Femtosecond Spectral Interferometry

    Dual quadrature femtosecond spectral interferometry is used to measure the gradient length, the peak temperature, and collision frequencies around critical density of an ultra-short pulse laser-produced plasma.

    Disorder in Solids Studied on an Ultrashort Timescale using Femtosecond X-Ray Diffraction

    We’ve studied the sub-picosecond response of an organometallic Langmuir-Blodgett film to an ultrashort laser excitation using ultrafast time-resolved x-ray diffraction. The ultrafast and monochromatic Kα x-ray so...

    Reflection and Transmission of High Intensity Femtosecond Laser Pulse Focused on Very Thin Plastic Foils

    The 150 fs pulse of the LOA Ti:Sapphire laser has been focused at an intensity of 5×1017 W/cm2 on a 800Å plastic foil. The reflected and transmitted laser radiation resulted strongly affected by Self Phase Modula...

    Influence of the Prepulse on the X-Ray Yield of a Subpicosecond Laser-Produced Plasma

    The development of lasers delivering ultra-short pulses at the multigigawatt power level opens new perspectives for the study of laser-matter interaction at very high intensities. When an intense ultra-short p...
