Title: Free electron laser pumped by a powerful traveling electromagnetic wave
Author: Kehs, R.; Carmel, Yuval; Granatstein, Victor; Destler, William
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,,.
