Ultra-Fast High-Precision Metallic Nanoparticle Synthesis using Laser-Accelerated Protons.

ABSTRACT: Laser-driven proton acceleration, as produced during the interaction of a high-intensity (I > 1 × 10¹⁸ W/cm²), short pulse (<1 ps) laser with a solid target, is a prosperous field of endeavor for manifold applications in different domains, including astrophysics, biomedicine and materials science. These emerging applications benefit from the unique features of the laser-accelerated particles such as short duration, intense flux and energy versatility, which allow obtaining unprecedented temperature and pressure conditions. In this paper, we show that laser-driven protons are perfectly suited for producing, in a single sub-ns laser pulse, metallic nanocrystals with tunable diameter ranging from tens to hundreds of nm and very high precision. Our method relies on the in
