A new helical optical klystron, UNKO-3, for a UV-free electron laser has been installed and commissioned on the UVSOR storage ring, Okazaki. Lasings at a visible wavelength region around 470 nm and a UV region down to 260 nm were obtained in test experiments. It was found that the mirror degradation rate with radiation from a helical mode was several tens of times slower than that with a planar mode.
