  UVSOR, a 750 MeV synchrotron light source of 53m circumference had been operated for more than 20 years. After a major upgrade in 2003, this machine was renamed to be UVSOR-II. The ring is now routinely operated with low emittance of 27 nm-rad and with four undulators, two in-vacuum ones and two variably polarized ones. The injector and the beam transport line are being upgraded to be compatible with full energy injection, preparing for the top up operation in near future. A resonator type free electron laser is successfully operational in very wide range, from visible to deep UV, with high average power exceeding 1 W. A femto-second laser bunch slicing system was constructed by utilizing a part of the FEL system. Intense coherent terahertz radiation was successfully produced by the slicing. Coherent harmonic generation was successfully demonstrated by using the same laser system.
