Complete reconstruction of bound and unbound electronic wavefunctions in two-photon double ionization
To be complete, the characterization of the photoionization process of atoms and molecules requires the extraction of all quantum-mechanical phases and amplitudes. So far, complete experiments have accessed on...

Coherent control with a short-wavelength free-electron laser
Researchers demonstrate correlation of two colours (63.0 and 31.5 nm wavelengths) in a free-electron laser and control photoelectron angular distribution by adjusting phase with 3 attosecond resolution.

Full tunability of laser femtosecond high-order harmonics in the ultraviolet spectral range
We demonstrate experimentally the full tunability of a coherent femtosecond source in the whole ultraviolet spectral region. The experiment relies on the technique of high-order harmonic generation driven by a...
