Abstract

Research in plasmonics has triggered intriguing studies of nonlinear photoemission from metallic nanostructures during the past decade. This has led to new avenues in electron microscopy, including the generation of attosecond electron pulse trains [1] and the probing of the electromagnetic near fields with attosecond resolution. Recent demonstrations of the photoemission of strongly Coulomb-correlated few-electron number states from metal nanotips open up interesting perspectives for enhancing the nonlinearity of multiphoton electron emission by increasing the electron number. Here, we explore this route in interferometric studies of multiphoton emission from sharp metal tips using few-cycle near-infrared pulses at 2 µm. We demonstrate multiphoton emission with up to 19th order and essentially single peak autocorrelation traces with sub-fs peak width. Studies of the carrier-envelope phase dependence of the photoemission suggest generation of isolated attosecond electron pulses in the multiphoton regime.
