Bandwidth and frequency enhancement of free electron laser in a mildly relativistic electron beam
Abstract
The bandwidth and frequency enhancement of the free electron laser instability in a mildly relativistic (gamma approximately less than 1.15) electron beam propagating through a dielectric loaded waveguide is presented. For an appropriate choice of the dielectric constant epsilon and the thickness of the dielectric material, it is shown that the instability bandwidth and frequency can be greatly enhanced for specified values of the beam energy and the wiggler wavelength.
