Abstract :
The FEL system of Laboratory for Electron Beam Research and Application (LEBRA) at Nihon University has provided relatively high FEL gain around 10% at the wavelength of 1.5 μm. The numerical estimation of the FEL gain suggests that LEBRA-FEL system has a sufficient performance on the electron beam bunching.
ition, the amplification of the third harmonics accompanying the intense fundamental FEL has been observed and the spectra of which have been measured. The experimental result indicates that the phenomenon is a kind of nonlinear harmonic generation.
