Kind: research · Impact: low

## In 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.
