    Two-stage seeded soft-X-ray free-electron laser

    We report the first generation of coherent, tunable, variable-polarization, soft X-ray femtosecond pulses, generated by a seeded free-electron laser (FEL) operating in the fresh bunch, two-stage harmonic upshi...

    Highly coherent and stable pulses from the FERMI seeded free-electron laser in the extreme ultraviolet

    Free-electron lasers (FELs) are promising devices for generating light with laser-like properties in the extreme ultraviolet and X-ray spectral regions. Recently, FELs based on the self-amplified spontaneous e...
