The Quantum X-ray Compton Free Electron Laser
The quantum operation mode in the X-ray Compton free-electron laser (FEL) is presented. This FEL mode emerges when the quantum emission exceeds the electron beam energy spread and FEL homogeneous linewidth, determined by the optical undulator length. Such a FEL becomes a two-level quantum oscillator with a completely inverted active medium. In the nonlinear interaction regime, inversion can be ...
متن کاملQuantum effects with an x-ray free-electron laser.
A quantum kinetic equation coupled with Maxwell's equation is used to estimate the laser power required at an x-ray free-electron laser (XFEL) facility to expose intrinsically quantum effects in the process of QED vacuum decay via spontaneous pair production. A 9 -TW-peak XFEL laser with photon energy of 8.3 keV could be sufficient to initiate particle accumulation and the consequent formation ...
متن کاملVIEWPOINT 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...
