VIEWPOINT Free - Electron Laser Does
L ight is perhaps the pre-eminent scientific tool, not just for observing objects but also for manipulating them. Near the visible part of the spectrum, conventional laser light is especially important thanks to its coherence and tunability, which give scientists fine control of the light beam in space and frequency. But conventional lasers do not operate in the extreme ultraviolet (XUV) wavele...
متن کاملAnomalous free electron laser interaction
Free electron lasers (FELs) are considered, typically, as fast wave devices. The normal FEL interaction satisfies the tuning condition oDðkz þ kWÞVz , where o and kz are the em-wave angular frequency and longitudinal wave number, respectively, Vz is the electron axial speed, and kW is the wiggler periodicity. This paper presents an anomalous FEL interaction, which may occur in slow-wave FELs (i...
متن کاملIntegrated free-electron laser schemes
The integrated-FEL concept is proposed as an alternative approach for the discrete compact-FELs [1]. In the proposed integrated-FEL, the accelerator and the wiggler are integrated for the sake of compaction. Two examples of integrated-FEL schemes are presented here briefly in order to demonstrate the FEL-integration concept: a) A functional integration scheme is shown in fig. 1. Two electron be...
متن کاملDynamics of Electrons in Free Electron Laser with Square Core Waveguides
Due to sensitive and important applications of free-electron laser in industry and medicine, improvement of the power and efficiency of laser has always been emphasized. Therefore, understanding the created field and examining the properties of the field in waveguides with different shapes and studying the sustainability of electrons movement are particularly important. In this study, the beh...
متن کاملOptimization of a Terawatt Free Electron Laser∗
There is great interest in generating a terawatt (TW) hard X-ray free electron laser (FEL) that will enable coherent diffraction imaging of complex molecules like proteins and probe fundamental high-field physics. A feasibility study of producing such pulses was carried out employing a configuration beginning with an SASE amplifier, followed by a “self-seeding” crystal monochromator, and finish...
