Performance study of a soft X-ray harmonic generation FEL seeded with an EUV laser pulse
نویسنده
چکیده
The performance of a free electron laser (FEL) using a low-power extreme ultraviolet (EUV) pulse as an input seed is investigated. The parameters are appropriate for 30 nm seeds produced from high-power Ti:Sapphire pulses using high harmonic generation schemes. It is found that, for reasonable beam parameters, robust FEL performance can be obtained. Both time-independent and time-dependent simulations are performed for varying system parameters using the GENESIS simulation code. A comparison is made with a two-stage harmonic FEL that is seeded by a high-power Ti:Sapphire pulse. ! 2007 Elsevier B.V. All rights reserved. PACS: 41.60.Cr; 29.27.!a

متن کاملFirst operation of a harmonic lasing self-seeded free electron laser
Harmonic lasing is a possible mode of operation of X-ray FEL user facilities that allows us to provide brilliant beams of higher energy photons for user experiments. Another useful application of harmonic lasing is the so-called harmonic lasing self-seeded free electron laser (HLSS FEL) that allows the improvement of spectral brightness of these facilities. In the past, harmonic lasing has been...
متن کاملEffects of Energy Chirp on Echo-enabled Harmonic Generation Free-electron Lasers∗
Due to the lack of coherent seed at the x-ray wavelengths, a SASE FEL is the most straightforward method to build an x-ray FEL. However, the temporal coherence of a SASE FEL is limited because the process starts from electron shot noise. To overcome this limitation, an ultraviolet seed laser may be used to interact with the electron beam in order to create density modulations at higher harmonic...
متن کاملSeeding of a soft-x-ray laser in a plasma waveguide by high harmonic generation.
A strongly saturated waveguide-based optical-field-ionization soft-x-ray laser seeded by high harmonic generation was demonstrated for Ni-like Kr lasing at 32.8 nm. Compared with the same laser seeded only with spontaneous emission, seeding with high harmonics yields much smaller divergence, enhanced spatial coherence, and controlled polarization. The integration of high harmonic seeding, optic...
متن کاملFeasibility study for a seeded hard x-ray source based on a two-stage echo-enabled harmonic generation FEL∗
We propose and analyze a scheme to achieve a seeded hard x-ray source based on a two-stage echo-enabled harmonic generation (EEHG) FEL. In the scheme an 180 nm seed laser covering the whole bunch is first used to modulate the beam when beam energy is 2 GeV. After passing through a strong chicane complicated fine structures are introduced into the phase space. The beam is again modulated by a sh...
