Abstract
We report on the measurement of XUV harmonic spectra between 53nm and 17nm wavelength emitted from solid targets driven by a short pulse (30fs FWHM) PW laser with peak intensity up to 6 x 10^21 W/cm2. Experiments were carried with a variety of target materials (metal foils, plastic foils, glass substrates), thicknesses (tens of nm to micron range) and laser parameters. This allowed us to study the influence of these parameters on the harmonic emission and gain insight into the interaction of the pump laser with the target front surface, where most of the energy absorption takes place. We explore the correlation between the dynamics on this target region and the proton acceleration from the laser target interaction by complementing the XUV spectrum measurements with simultaneous proton spectra for the different aforementioned conditions.
