By combining a coherent control scheme with photoelectron spectroscopy, we generated and detected lateral electron currents at a metal surface on a femtosecond time scale with a contact-free experimental setup. We used coherent optical excitation at the light frequencies ωa and ωa/2 to induce the current, whose direction was controlled by the relative phase between the phase-locked laser excitation pulses. Time- and angle-resolved photoelectron spectroscopy afforded a direct image of the momentum distribution of the excited electrons as a function of time. For the first (n = 1) image-potential state of Cu(100), we found a decay time of 10 femtoseconds, attributable to electron scattering with steps and surface defects."}],"publication_identifier":{"issn":["0036-8075","1095-9203"]},"date_updated":"2023-04-21T22:39:40Z","_id":"23488","doi":"10.1126/science.1146764","type":"journal_article","user_id":"49063","date_created":"2021-08-24T09:09:39Z","page":"1287-1291","publication_status":"published","language":[{"iso":"eng"}],"volume":318,"department":[{"_id":"15"},{"_id":"170"},{"_id":"293"},{"_id":"230"}],"status":"public","author":[{"first_name":"J.","last_name":"Gudde","full_name":"Gudde, J."},{"last_name":"Rohleder","full_name":"Rohleder, M.","first_name":"M."},{"id":"344","last_name":"Meier","full_name":"Meier, Torsten","orcid":"0000-0001-8864-2072","first_name":"Torsten"},{"first_name":"S.
