  Construction and development of a source development station are in progress
at UVSOR-III, a 750 MeV electron storage ring. It is equipped with an optical
klystron type undulator system, a mode lock Ti:Sa Laser system, a dedicated
beam-line for visible-VUV radiation and a parasitic beam-line for THz
radiation. New light port to extract edge radiation was constructed recently.
An optical cavity for a resonator free electron laser is currently being
reconstructed. Some experiments such as coherent THz radiation, coherent
harmonic radiation, laser Compton Scattering gamma-rays and optical vortices
are in progress.
