Real-time observation of a correlation-driven sub 3 fs charge migration in ionised adenine

20 May 2021

Our group (CFEL-ATTO) with the key participation of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) has demonstrated that ultrashort laser pulses can be used to protect one of the DNA building blocks against destruction induced by vacuum ultraviolet (VUV) radiation. We unveiled that a second laser flash in the infrared, timed shortly (only a few millionths of billions of a second) after the first VUV flash, prevented the adenine molecule to disintegrate, therefore stabilising it. We presents our work in the journal Communications Chemistry published by Nature publishing group.

HELIOS Helmholtz-Lund International Graduate School

19 January 2021

On January 19th we had our virtual launch event with talks on instrumentation challenges in atomic, laser, particle and nano-bio physics. Our first cohort of PhD students gave interesting and engaging presentations about their projects. We are proud to have assembled such a talented and multi-disciplinary team, which will further grow over the coming years.

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.

Record compression delivers ultra-short laser pulses

06 May 2020

The CFEL-ATTO group collaborated in an experiment to compress a high-average-power laser’s high-energy pulses from 1.2 ps down to 13 fs duration, opening up new possibilities for ultrafast physics and plasma acceleration.
