Probing of optical near-fields by electron rescattering on the 1 nm scale
Sebastian Thomas, Michael Krüger, Michael Förster +2
We present a new method of measuring optical near-fields within ~1 nm of a metal surface, based on rescattering of photoemitted electrons. With this method, we precisely measure th…
Strong-field above-threshold photoemission from sharp metal tips
Markus Schenk, Michael Krüger, Peter Hommelhoff
We present energy-resolved measurements of electron emission from sharp metal tips driven with low energy pulses from a few-cycle laser oscillator. We observe above-threshold photo…
Spectroscopy of formaldehyde in the 30140-30790cm^-1 range
Michael Motsch, Markus Schenk, Martin Zeppenfeld +4
Room-temperature absorption spectroscopy of formaldehyde has been performed in the 30140-30790cm^-1 range. Using tunable ultraviolet continuous-wave laser light, individual rotatio…
Electron rescattering at metal nanotips induced by ultrashort laser pulses
Georg Wachter, Christoph Lemell, Joachim Burgdörfer +3
We report on the first investigation of plateau and cut-off structures in photoelectron spectra from nano-scale metal tips interacting with few-cycle near-infrared laser pulses. Th…
Attosecond control of electrons emitted from a nanoscale metal tip
Michael Krüger, Markus Schenk, Peter Hommelhoff
Attosecond science is based on steering of electrons with the electric field of well-controlled femtosecond laser pulses. It has led to, for example, the generation of XUV light pu…
