Tīmeklis2024. gada 16. jūn. · The FERMI laser at Elettra-Sincrotrone Trieste in Italy is a novel class of FEL that is first seeded by an external conventional ultraviolet laser. Seeding the FEL enhances the longitudinal coherence of the pulses, which enhances stability, temporal coherence, and bandwidth. TīmeklisFERMI is a seeded FEL based on the High-Gain harmonic generation (HGHG) scheme [16]. It features two FEL beamlines, a single stage cascade FEL-1 [17] and a double-stage for FEL-2 [18]. The necessary electron beam for the production of the photons is provided by a normal conducting linac [19]. All the presented results were obtained …
Tīmeklis2003 - 2015. The FERMI light source is a novel and advanced free electron laser based on the HGHG (High Gain Harmonic Generation) external coherent seeding. Design for generating fully coherent EUV and soft X-ray pulses, today FERMI is a unique FEL source worldwide considered as the solely generating fully coherent EUV and soft X … TīmeklisLaser Technology and Optics (Innovative lasing schemes) We demonstrated high-gain EEHG lasing producing stable, intense, nearly fully coherent pulses at wavelengths as short as 5.9 nm (211 eV) at the FERMI FEL. Observation of stable, narrow-band, coherent emission down to 2.6 nm (~474 eV) make the technique a prime candidate …
