Abstract

Free-electron laser oscillation around 270 nm has been demonstrated on the UVSOR storage ring. In order to overcome an increase of cavity losses due to a shorter wavelength, the FEL gain was enhanced by reducing beam energy from an ordinal value of 500 to 430 MeV. We have investigated the reflectance of dielectric multilayer mirrors in the UV, fabricated by deposition techniques of electron-beam evaporation and ion-beam sputtering. A possibility of high-reflectance multilayer at shorter wavelength is discussed.
