ABSTRACT
Stable, single-mode, linearly polarized emission has been achieved with a free-electron laser (FEL) oscillator for pulses of up to 30 μs when gain differences are used to select between a limited number of cavity modes. The frequency- and phase-modulation noise spectra are monitored by heterodyning and homodyning techniques, and the measured linewidth is near 70 kHz at 31 GHz. The FEL oscillator mechanism is inherently frequency stable and step tunable over a practical range of control parameters determined primarily by the stability of the electron beam voltage.
