Attosecond Science

Real time observation of electron dynamics in matter

We develop 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.

Recent highlights

Controlled strong-field ionization in Lithium Niobate

10 July 2020

The CFEL-ATTO group collaborated in experiments aimed at controlling the ionization of LiNbO3 with strong-field lasers, gaining new insights on the role of microscopic material properties in this fundamental process through femtosecond laser-ablation, a technique often employed in high-resolution micromachining of materials.
