Free electron laser pumped by a powerful traveling electromagnetic wave

Abstract: A three-wave free-electron laser (FEL) was operated with a powerful 8.4-GHz electromagnetic "pump" wave replacing the usual magnetostatic wiggler. The presence of a uniform axial magnetic field B,, produced cyclotron-harmonic "idler" waves. Peaks in the emission spectrum corresponding to cyclotron harmonics were observed covering a frequency range from 16.5 to 130 GHz. The frequency spectrum of this novel FEL mechanism was tuned continuously by the variation of B,,.

“…Employment of high-power microwaves and lasers as wigglers in a free-electron laser (FEL), to produce much shorter wavelengths, is an attractive proposition (Khes et al 1990 ;Esarey and Sprangle 1992 ;Sprangle et al 1992). The wavelength λ L of the radiation generated is related to that of the wiggler, λ !…”
