Attosecond Science
Real time observation of electron dynamics in matter
The CFEL-ATTO Group develops advanced attosecond technologies to investigate the light-activated dynamics of matter with extreme time resolution. In particular, the main goal of our research is to track and ideally control the electronic motion in systems of increasing complexity, from simple molecules to biochemically relevant molecules and nanoparticles.

A new experimental approach provides the long-awaited tools to understand the role of electrons in the molecular chiral reactivity and offers a way to control physical and chemical properties that result from chiral interactions. The study, published in the journal “Nature”, was led by Universität Hamburg and DESY as part of a collaboration with the Centre Laser Intense et Applications (CELIA) and the Laboratoire de Chimie et Physique Quantiques (LCPQ) in France and the Max Born Institute in Berlin.

The CFEL-ATTO team was part of an international collaboration between DESY, Stanford University, the Max-Planck Institute of Quantum Optics (MPQ) and the University of Hamburg, for which the results on plasmonic field sampling have just been published in Nano Letters. In this work we report the direct sampling of an emerging plasmonic field on the petahertz scale, using a technique which allows to characterize an electric field directly in the time domain with subcycle resolution. The observations may lead to new insights in the fields of nanophotonics and energy conversion.

Members of the CFEL-ATTO group have collaborated with the group of Prof. Roberto Oselame from the Institute for Photonics and Nanotechnologies CNR-IFN in Milan (Italy) to develop a novel differentially-pumped integrated glass chip for the efficient generation of ultrashort UV radiation using Third Harmonic Generation. The results have been published in JPhys Photonics as a contribution to the special issue 'Emerging Leaders 2024'.
