Laboratory for Non-linear Optics (LNO)
We develop and operate state-of-the-art laser systems for driving the high brightness electron source of the Hard X-ray Swiss Free Electron Laser (SwissFEL), and for pump-probe experiments at the photon-science beamlines. We improve and extend these systems according to the user requirements.
We pursue in-house research activities at the Hard X-ray Swiss Free Electron Laser (SwissFEL) and Swiss Light Source (SLS) beamlines exploiting LNO’s laser facilities. We perform R&D on laser-driven electron sources in close collaboration with PSI’s accelerator division.

High-resolution ptychographic imaging at a seeded free-electron laser source using OAM beams
Electromagnetic waves possessing orbital angular momentum (OAM) are powerful tools for applications in optical communications, quantum technologies, and optical tweezers. Now, a consortium of collaborators in France, Italy, Slovenia, Spain, Switzerland, Sweden, and the US reports on using such beams in the extreme ultraviolet region for ptychographic imaging in the cover page article of Optica 11, Issue 3. By controlling the topological charge, the researchers achieve an improvement of 30% in image resolution.
SwissFEL: a next generation tool for Attosecond Science
The 2023 Nobel Prize in Physics recognises attosecond science’s pioneers. Past and future, this field’s evolution is entwined with SwissFEL.
Réparer les dommages héréditaires avec la lumière du soleil
En utilisant des stimulations mécaniques, les scientifiques du PSI ont reconverti des cellules de tissus conjonctifs en cellules semblables à des cellules souches, avant de les transplanter dans des tissus cutanés lésés. Cela a permis d’accélérer la régénération de la peau et la cicatrisation des plaies.
