Effect of the composition and wavelength on strong-field photoelectron emission from plasmonic nanoparticles

POSTER

Abstract

We explore the generation of photoelectrons (PEs) by exposure of plasmonic nanoparticles to intense infrared laser pulses. We assess the material and wavelength dependence of PE spectra and destinguish direct and rescattered photoemission pathways. To conduct this analysis, we experimentally measured [1] and numerically simulated [2,3] the momentum distributions of emitted PEs from spherical gold, silver, and platinum nanoparticles (NPs) ranging in size from 2.5 to 50 nm in radius for peak intensities between 0.1×1013 and 3.0 ×1013 W/cm2 and wavelengths ranging from 500 nm to 1800 nm.
