Lasers , Free - Electron

Free-electron lasers are radiation sources, based on the coherent emission of synchrotron radiation of relativistic electrons within an undulator or wiggler. The resonant radiation wavelength depends on the electron beam energy and can be tuned over the entire spectrum from micrometer to X-ray radiation. The emission level of free-electron lasers is several orders of magnitude larger than the e...

High-Gain Free Electron Lasers Using Induction Linear Accelerators

High-power free electron lasers (FEL’s) can be realized using induction linear accelerators as the source of the electron beam. These accelerators are currently capable of producing intense cwrents (102-104 A) at moderately high energy (1-50 MeV). Experiments using a 500 A, 3.3 MeV beam have produced 80 MW of radiation at 34.6 GHz and are in good agreement with theoretical analysis. Future expe...
