Abstract

It is proposed to use longitudinal electrostatic undulator as transit section in an active Free Electron Laser of klystron type for multiharmonic space change waves (SCW) amplification. The quadratic nonlinear theory of such section has been constructed. It was found that the effect of plural three-wave parametric resonances is realized in the investigated system. The SCW harmonics growth increment were obtained and analyzed. It was found that the increment has the same value for the first as well as the higher SCW harmonics. It is shown that the considered system is promising as an efficient multi-harmonic SCW amplifier for the waves with complex spectrum.
