Cross-process interference in single-cycle electron emission from metal needle tips
Anne Herzig, Peter Hommelhoff, Eleftherios Goulielmakis +2
Though interference from different emission channels enabled a deeper understanding of strong-field photoemission in atoms and molecules, it remained out of reach for solids. Here,…
Dichography: Two-frame Ultrafast Imaging from a Single Diffraction Pattern
Linos Hecht, Andre Al Haddad, Björn Bastian +47
We experimentally demonstrate that pairs of time-delayed ultrabright and ultrashort X-ray pulses of two different colors, delivered by modern X-ray Free Electron Lasers, can provid…
