Intracycle Interference in Strong-Field Photoemission from a Tungsten Needle Tip
feeds.aps.org · By Timo Wirth, Jonas Heimerl, Stefan Meier & Peter Hommelhoff ·
The Brief
- A paper by Timo Wirth, Jonas Heimerl, Stefan Meier and Peter Hommelhoff studies strong-field photoemission from a tungsten needle tip.
- The work concerns intracycle interference of electron wave packets, which shapes spectral peaks in photoemission driven by strong laser fields.
- Electrons photoemitted by strong laser fields can rescatter and generate attosecond high harmonics, according to the source abstract.
Why it matters
The study refines understanding of how coherent electron wave packets interfere within a single laser cycle, a process relevant to attosecond physics and high-harmonic generation from nanoscale emitters.
Who’s affected
- attosecond and ultrafast physicists
- researchers working on strong-field photoemission and nanotip electron sources
