FREE-ELECTRON LASER DRIVEN BY FIBER LASER-BASED LASER PLASMA ACCELERATOR

摘要

A Free Electron Laser source includes: a fiber-based laser having a plurality of amplifying fibres wherein an initial laser pulse is distributed and amplified, and element for grouping together the elementary pulses amplified in the fibre in order to form an a single amplified global laser pulse; a laser plasma accelerator wherein the global laser pulse generates relativistic electron beams, a beam focusing system transporting electron beams from the laser plasma accelerator, an undulator wherein relativistic electron beams generate an electromagnetic beam, and a beam separator system, wherein the electron beam and the electromagnetic beam are separated.
