Abstract

Optical-Klystron free electron lasers operating with undulators having opposite circular polarizations are characterized by a spontaneous emission spectrum which does not exhibit the characteristic interference pattern. The use of the Madey theorem may allow the conclusion that, for such configuration, the dispersive section does not provide any gain enhancement. In this paper we analyse the problem from a dynamical point of view and clarify how the optical field evolve, what is the role of the bunching and how the dynamics of the system can be followed up to the saturation. © 2001 Published by Elsevier Science B.V.
