Résumé

Solid targets have been irradiated by 80 fs laser pulses at 10¹⁷ W/cm² laser irradiance. Spectra obtained in the 0.7-0.9 nm wavelength range show that x-ray emission occur at near solid electron densities (Ne ∼ 10²³ cm^-3). The analysis of the Kα emission line points out the role of hot, fast electrons in the interaction physics. A time-resolved Schlieren imaging technique shows that the ultra-short laser pulse strikes a pre-plasma created by the laser amplified spontaneous emission (ASE) with an electron density gradient scale length less than 1 μm.
