This paper reports a three-wave free-electron laser (FEL) operated with a powerful 8.4-GHz electromagnetic pump wave replacing the usual magnetostatic wiggler. The presence of a uniform axial magnetic field {ital B}{sub 0} 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 FEL mechanism was tuned continuously by the variation of {ital B}{sub 0}.
