Strong-field photoemission from nanostructuresdriven by few-cycle mid-infrared fields
We present strong-field photoemission from plasmonic nanotips driven by ultrashort pulses at wavelengths of 0.8-8μm, reaching Keldysh parameters down to 0.1. We identify a sub-cycle acceleration regime that is exclusive to confined fields in nanostructures.
