Deadline: 22 February 2026
Ref: GA/26/3

_Background_

_Beamline / Project / Activity description_

The FERMI FEL is based on the high-gain harmonic generation (HGHG) seeding scheme and strongly relies on the use of ultrafast laser systems for the generation of the electron bunches (photoinjector laser, or PIL), suppression of microbunching instabilities (laser heater, or LH), seeding by tunable UV light (seed laser, or SL) and pump-probe experiments at the user stations (pulses derived from the seed laser, or SLU). The Elettra Laser Laboratory team provides full operational support and implements continuous refinement and upgrades of these systems to support the FEL source improvements. Recent examples are the implementation of the echo-enabled harmonic generation (EEHG) seeding scheme, as well as FEL2 operation reaching the oxygen K-edge by 200 nm seeding. Further emphasis on enhancing the performance of the seed pulses in this spectral region, i.e., 200 nm and below, is planned for the near future.



The Elettra Laser Laboratory team is also actively involved in the development and support of the set-ups for user experiments using combined FEL/external laser pulses for pump-probe experiments. A task of growing importance for the Elettra Laser Laboratory is also the support of laser systems related to the ongoing Elettra 2.0 facility upgrade. An important first step in this respect is operational support and further development of the two tunable deep-UV narrowband lasers installed in the new Elettra Inelastic Ultraviolet Scattering (IUVS) laboratory.
