Investigation on laser–plasma coupling in intense, ultrashort irradiation of a nanostructured silicon target

Abstract: One of the most interesting research fields in laser-matter interaction studies is the investigation of effects and mechanisms produced by nano-or micro-structured targets, mainly devoted to the enhancing of laser-target or laser-plasma coupling. In intense and ultra-intense laser interaction regimes, the observed enhancement of x-ray plasma emission and/or hot electron conversion efficiency is explained by a variety of mechanisms depending on the dimensions and shape of the structures irradiated. In the prese… Show more

“…Nanostructures on the targets surface, based on metallic nanowires (NWs) embedded in porous alumina [16], can be useful since they can absorb light at very high efficiency. These expectations are confirmed from experiments in different laser pulses regimes (from ns to fs) and various intensities [17,18].…”

“…An established branch of high-energy density laser-matter interaction physics combines geometrical and material properties of the targets used in order to absorb most of the laser energy and to redistribute it with the highest efficiency into directional electron or ion currents, shock waves, quasistatic fields, radiation, or other daughter effects. Several approaches have been already proved to be very efficient in terms of laser radiation absorption: nanoclusters [1,2], foams [3,4,5], structured targets [6,7,8,9], or more tricky setups [10]. There, a target design defines predominant channels for efficient energy deposition.…”
