A 750 MeV synchrotron light source, UVSOR-II, is routinely operated for users with emittance of 27 nm-rad, which is the world smallest among the operational synchrotron light sources of relatively low energy below 1 GeV. Eight bending magnets and three undulators provide synchrotron light to totally 13 beam-lines. Two of the undulators are of in-vacuum type and another is of variable polarization type. A high performance monochromator for the beam-line, BL3U, and a high-resolution photoelectron energy analyzer for the end station at BL5U have been successfully installed, both of which utilize undulator radiation. The IR beam-line, BL6B has been upgraded by introducing a so-called magic mirror as the first mirrors and the world-highest intensity has been successfully achieved. Fourth undulator of variable polarization type and its beam-line are under construction. The energy upgrade of the injector is in progress, to realize the top-up operation within a few years. The wavelength of the free electron laser has come into the deep UV region, thanks to the low emittance of the ring. Some users' experiments are in progress. A Ti:Sa laser for the laser-bunch slicing experiments was installed. Intense coherent terahertz radiation produced by the laser e-beam interaction has been successfully detected.
