FERMI

FERMI (Free Electron laser Radiation for Multidisciplinary Investigations) is a seeded free electron laser (FEL) source operating at Elettra Sincrotrone Trieste. FERMI is an international user facility for scientific investigations ranging from chemistry to condensed matter physics and from advanced technology to biology.
Among existing FEL sources FERMI is unique in many respects. The implemented seeded FEL scheme guarantees the generation of highly transversely and longitudinally coherent ultrashort (5-100 femtosecond) pulses in the wavelength range from 100 nm to 4 nm in the first harmonic. The use of APPLE II-type undulators allows for variable polarization, from completely linear both horizontally and vertically to circular in both directions.

• The seed laser provides a reference signal throughout the FERMI facility to facilitate the femtosecond level precision timing and synchronization of all systems.
• Two advanced light sources, the electron storage ring Elettra and the free-electron laser (FEL) FERMI are part of the Elettra Laboratory.
