Abstract:
In recent years, there is interest of the FEL community in external-seeding techniques such as the Echo-Enabled Harmonic Generation (EEHG) and the High Gain Harmonic Generation (HGHG). With these techniques, pulses of an improved temporal coherence are generated, but at the same time they are limited by the repetition rates that seed lasers can currently offer with the required pulse energies. A big challenge is to combine the advantages of seeding schemes with high repetition rates. For this purpose, we study a combination of a modulatoroscillator. The oscillator is used at a long wavelength to modulate the electron beam and an amplifier is operated to extract the FEL radiation of the desired harmonic. We present simulation results of a seeded oscillatoramplifier FEL in an HGHG scheme.
