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]

Ferenc Krausz is a Hungarian physicist renowned for his pioneering work in the field of attosecond physics. Born on May 17, 1962, he is best known for developing techniques to generate and control attosecond laser pulses, which are significantly shorter than traditional laser pulses and allow scientists to observe and study ultrafast processes at the atomic and molecular levels.
