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...

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...
