Paper Abstract

By making use of the parametric-amplifier model,this paper analyses the effect of the space-charge waves in Raman free electron laser with an axial guide field, it is shown that without taking the initial transverse velocity into account, kW vZO <wC is a necessary condition under which the scattered wave couples the slow space-charge wave. The dispersion relation and gain of the scattered wave,as well as the matching condition between the scattered wave and the space-charge wave, are derived.
