    Abstract

    Large-amplitude electromagnetic radiofrequency fields are created by the charge-separation induced in interactions of high-intensity, short-pulse lasers with solid targets and have intensity that decreases with the distance from target. Alternatively, it was experimentally proved very recently that charged particles emitted by petawatt laser-target interactions can be deposited on a capacitor-collector structure, far away from the target, and lead to the rapid (nanoseconds scale) generation of large quasi-static electric fields (MV/m), over wide regions. We demonstrate here the generation of both these two type of fields in experiments at the PHELIX Laser, with ∽100 J energy and ∽10<sup>19</sup> W/cm<sup>2</sup> intensity, for picoseconds laser pulses. Quasi-static fields, up to tens of kV/m, were here observed at distances larger than 1 m from target and resulted much higher than the radiofrequency component. This is of primary importance for inertial-confinement-fusion and laser-plasma-acceleration and also for promising applications to different scenarios.
