Anne L'Huillier Created 2026-10-24 Updated 2026-11-05
Anne L'Huillier develops experimental and theoretical methods based on high harmonic generation in gases. The generated extreme ultraviolet light contains many harmonics of the driving laser frequency; their relative spectral phases determine whether they combine into short optical pulses. Her research connects that generation problem with attosecond measurements of electron dynamics following photoionization. The central link is between a controlled optical waveform and the timing information carried by emitted electrons.[ref]

Ferenc Krausz Created 2026-10-18 Updated 2026-11-05
Ferenc Krausz coauthored a 2001 demonstration of attosecond timing using photoionization. A synchronized visible electric field changes the energy distribution of photoelectrons released by a soft-X-ray optical pulse. Scanning their relative delay converts an otherwise inaccessible time interval into a measured electron spectrum. The report inferred a soft-X-ray duration of attoseconds and demonstrated an instrument for probing electron dynamics on that scale.[ref]

An experimental optical physicist who coauthored attosecond pulse measurements. Combining a short extreme-ultraviolet excitation with a synchronized optical field lets emitted photoelectrons carry information about the pulse's timing. This makes a subfemtosecond optical event measurable through an electron-energy distribution rather than by an electronic stopwatch.[ref]

Pierre Agostini Created 2026-10-18 Updated 2026-11-05
Pierre Agostini coauthored the measurement of a train of attosecond optical pulses synthesized from high harmonic generation. Measuring only the harmonic intensities does not determine the pulse train: the relative spectral phases are also needed. Their two-colour photoionization measurement recovered those spectral phases, giving reconstructed peaks about 250 attoseconds wide. This joined generation with a measurable test of temporal structure, rather than inferring a short pulse solely from a broad optical spectrum.[ref]
