Chirped pulse amplification at VISA-FEL
نویسندگان
چکیده
Chirped beam manipulations are of the great interest to the FEL (Free Electron Laser) community as potential means of obtaining ultra short X-ray pulses. The experiment is under way at the ATF (Accelerator Test Facility) at BNL (Brookhaven National Laboratory) to study the FEL process limits with the under-compressed chirped electron beam. High gain near-saturation SASE operation was achieved with the strongly chirped beam (~ 2.8% head-to-tail). The measured beam dynamics and SASE properties are presented, as well as the design parameters for the next round of experiment utilizing the newly installed UCLA/ATF chicane compressor. PACS codes: 41.60.Cr

Chirped Pulse Amplification of HGHG-FEL at DUV-FEL Facility at BNL
The DUV-FEL facility has been in operation in High Gain Harmonic Generation (HGHG) mode for one year producing 266 nm output from 177 MeV electrons. In this paper we present preliminary results of the Chirped Pulse Amplification (CPA) of HGHG radiation. In the normal HGHG process, a 1 ps electron beam is seeded by chirped 9 ps long 800 nm Ti:Sapphire laser. The electron beam sees only a narrow ...
متن کاملA Chirped-pulse Regenerative-amplifier Fel for the Gamma-gamma Collider*
During a Workshop on Gamma-Gamma Colliders in Lawrence Berkeley Laboratory, it was pointed out that an 1μm laser that can produce 1-J, 1-ps pulses at a few hundred hertz is required. With high-power scalability and ease of formatting, an FEL can be a promising candidate for such a laser. We propose an FEL scheme based on chirped-pulsed regenerative amplification to achieve this high peak-power ...
متن کاملExperimental study of a high-gain harmonic-generation free-electron laser in the ultraviolet
050701-1 Saturation of a high-gain harmonic-generation free-electron laser (HGHG-FEL) at 266 nm has been accomplished at the Brookhaven National Laboratory/Deep Ultra Violet Free Electron Laser Facility (BNL/DUV-FEL) by seeding with an 800 nm Ti:sapphire laser. We describe the diagnostics used to characterize the electron beam and the FEL output. Analytic and simulation calculations of the HGHG...
متن کاملThree-Dimensional Analysis of Frequency-Chirped FELs
Frequency-chirped free-electron lasers (FELs) are useful to generate a large photon bandwidth or a shorter xray pulse duration. In this paper, we present a threedimensional analysis of a high-gain FEL driven by the energy-chirped electron beam. We show that the FEL eigenmode equation is the same for a frequency-chirped FEL as for an undulator-tapered FEL. We study the transverse effects of such...
متن کاملVisa Ib: Ultra-high Bandwidth, High Gain Sase Fel
We report the results of a high energy spread SASE FEL experiment, the intermediary experiment linking the VISA I and VISA II projects. A highly chirped beam (1.7 %) was transported, without corrections of longitudinal aberrations in the ATF dogleg, and injected into the VISA undulator. The ouput radiation displayed an uncharacteristicly large bandwidth (12 %) with extremely stable lasing and m...
