High-energy gamma rays produced by intracavity Compton backscattering of a free electron laser (FEL) on the UVSOR storage ring have been observed. In the experiment, the storage ring was operated at an electron energy of 600 MeV. The FEL wavelengths were 466 and 270 nm, and then maximum photon energies were calculated to be 14.6 and 25.2 MeV, respectively. Spectra of the photons measured by using a large NaI scintillation detector were found to be consistent with a theoretical calculation.
