TL;DR: In this article, the carrier-envelope phase of laser fields at metal tips can affect the generation and motion of strong-field emitted electrons, and observed variations in the width of plateau-like photoelectron spectra characteristic of the subcycle regime may lead to the control of coherent electron motion at metallic nanostructures on ultrashort lengths and timescales.

TL;DR: These results strongly suggest that these nanometer-sized ultrafast light spots will enable new experiments probing the dynamics of optical excitations of individual metallic, semiconducting, and magnetic nanostructures.

TL;DR: An essentially dispersion-free and diffraction-limited focusing of few-cycle laser pulses through all-reflective microscope objectives is demonstrated, of considerable interest for inducing and probing optical nonlinearities of individual nanostructures.

TL;DR: In this article, the effect of the near-field distribution of sharply etched, nanometer-sized gold tapers on angle-resolved kinetic energy spectra of electrons photoemitted by ultrafast laser pulse irradiation is investigated both experimentally and theoretically.

TL;DR: The realization of a source of 2-cycle laser pulses tunable between 1.2 and 2.1 μm, and with intrinsic CEP stability, is demonstrated by measuring kinetic energy spectra of photoemitted electrons from a single metal nanostructure and by observing a clear variation of the electron yield with the CEP.
