Welcome to the LACUS facility, an EPFL research center for femtosecond laser technology and adavanced spectroscopies. The LACUS logo is designed by Fayez Z. Chergui.

The Lausanne Centre for Ultrafast Science (LACUS) brings together the EPFL teams working in Ultrafast Science and Technology. LACUS offers user access to advanced ultrafast laser, X-ray and electron technologies and spectroscopy methods developed at EPFL. We aim at enabling EPFL and external researcher to build new experiments and technologies, using state-of-the-art femtosecond light and electron sources maintained by our team. Our light and electron sources complement and strengthen existing Swiss scientific infrastructures, e.g. the Swiss Light Source and the SwissFEL.
