Multicolor strong-field photoemission from metal nanotips — •Lara Wimmer, Georg Herink, Katharina Echternkamp, Daniel Solli, Sergej Yalunin, and Claus Ropers — Materials Physics Institute and Courant Research Centre, University of Göttingen, Friedrich-Hund-Platz 1, 37077 Göttingen

We study strong-field photoemission from plasmonic nanotips driven by ultrashort laser pulses over a large spectral range. External static and optical fields enable us to control the photoemission process in a variety of ways. In multicolor scenarios, the cross-coupling of driving pulses at different wavelengths is investigated theoretically and experimentally, and the potential for ultrafast gating and steering of electrons in nanostructures is demonstrated.
