Abstract:

The first visible linac free-electron-laser FEL oscillator has been operated above threshold at the wavelength of 526 nm with and without a taper. Peak output power of 170KW with a macropulse average power of 1.1 watts was observed. The cavity dielectric mirrors were damaged at approximately 140KW sq cm of average power in the presents of UV from the FEL harmonics. The gain and efficiency were much less than predicted due to developed wiggler field errors.
