A mid-infrared Free Electron Laser (FEL) named as Kyoto University FEL (KU-FEL) has been developed for energy-related research at Institute of Advanced Energy, Kyoto University. The wavelength range of KU-FEL is 3.6 - 23 mu m and opened for various user experiments. A compact THz-FEL, which consists of a photocathode RF gun, a bunch compressor, and an undulator, is now under construction. Present status and perspective of the FEL facility at Kyoto University is reported in this paper. (C) 2016 The Authors. Published by Elsevier B.V.
