The first linac-based visible free-electron-laser oscillator was operated in February 1987 at a wavelength of 525 nm with and without a wiggler taper. Peak output power of 29 kW with a macropulse average power of 1.1 W was observed. The cavity dielectric mirrors were damaged at approximately 21 kW/cm2 of average intracavity power.

    We present a method for enhancing the efficiency of a Free Electron Laser Maser oscillator by locking it to a preferred resonator mode. This is done by prebunching of the e beam before injection into the wiggler. In a free running oscillator, the longitudinal mode that dominates the mode...

    The stability of single-mode operation of free electron laser (FEL) oscillators is investigated. Two models of an untapered FEL oscillator are considered. The first model is called the klystron model. In the klystron model the FEL interaction occurs at two points: a prebunching point and an...
