Novel 'XFELO' laser system produces razor-sharp X-ray light A team of engineers and scientists has shown for the first time that a hard-X-ray cavity can provide net X-ray gain, with X-ray pulses being circulated between crystal mirrors and amplified in the process, much like happens with an optical laser. The result of the proof-of-concept at European XFEL is a particularly coherent, laser-like light of a quality that is unprecedented in the hard X-ray spectrum.

✨X-ray laser breakthrough! Scientists amplified X-rays in a loop, creating incredibly coherent light—a first! 🤯 Like an optical laser, but with X-rays! #XFEL 🔬

This groundbreaking work at #SwissFEL demonstrates a modelocked #XFEL producing coherent trains of attosecond X-ray pulses, enabling unprecedented control of light at the attosecond scale.

European XFEL: Am Hamburgischen Röntgenlaser wird es kalt Der European XFEL wird nach einer längeren Pause wieder für den wissenschaftlichen Betrieb vorbereitet. Wir waren vorher noch einmal dort.

Single Molecule Ultrafast X-Ray Diffraction

The project 'Theory and Algorithms for Structure Determination from Single Molecule X-Ray Scattering Images' aims at deriving priors for #Bayesian methods from atomistic simulations and #ML. It also offers the opportunity to work with data from the European #XFEL facility at #DESY t1p.de/oo8eu #job

Scientists Capture First Direct Image of a Single Electron in a Chemical Reaction

Scientists directly imaged a single valence electron in a reaction, using femtosecond X‑ray flashes from SLAC’s free‑electron laser on ammonia (NH₃). Read more: getnews.me/scientists-capture-first... #electron #xfel

Individual atoms tracked during real-time chemical bond formation Researchers at European XFEL in Germany have tracked in real time the movement of individual atoms during a chemical reaction in the gas phase. Using extremely short X-ray flashes, they were able to observe the formation of an iodine molecule (I₂) after irradiating diiodomethane (CH₂I₂) molecules by infrared light, which involves breaking two bonds and forming a new one.

🤯 Scientists *watched* atoms dance during a reaction! Real-time glimpses of molecules breaking & forming—a tiny, atomic ballet! ✨ #XFEL

Celebration of Pride Week 2025

At European XFEL, we are proud to be an international, science-driven community where individuality and #diversity are truly valued.
Several European #XFEL staff members have offered to share their stories about being LGBTQI+ in #STEM:

uh... there must be some great "time-resolved science meme" potential here... #XFEL folks? anyone? this feels like gold on a platinum platter

Sulbactam (yellow) is a β-lactamase inhibitor. It is able to bind in the active site and covalently bond to the catalytic serine, preventing BlaC from binding and cleaving new antibiotic substrates. The topmost light blue subunit is shown as semi-transparent to better visualize sulbactam binding.

Making lasers public: The European X-ray Free Electron Laser - Making Science Public Last weekend, my mum phoned me from Germany to tell me about the new x-ray laser inaugurated in Hamburg (as I later learned this is the European X-ray Free Electron Laser or XFEL) and asked me whether I had heard about it and whether I could explain what it did. I hadn’t and I couldn’t. ...
