Abstract

We have conducted oscillation experiments of a free electron laser on the UVSOR storage ring. In the experiments the storage ring was operated in the two-bunch mode at an electron energy of 500 MeV and an optical klystron was employed. Dielectric multilayer mirrors with high reflectivity at a wavelength around 455 nm were used for an optical resonator. When the beam current is higher than 9 mA/bunch, lasing started at 456 nm. The lasing wavelength can be varied in the region from 430 nm to 480 nm. The linewidth of the laser is approximately 0.2 nm. The peak power in micro-pulses transmitted by the front mirror is roughly estimated to be at least 0.8 W at a beam current of 23 mA/bunch.
