Abstract

We report high power emission (18 MW) at a wavelength of λ = 640 μm and a bandwidth ΔAλ/λ< 0.04 from a superradiant free electron laser (FEL) excited by a 2MeV, 1 kA electron beam. Comparison of the experiment with a nonlinear simulation yields good agreement. Theoretical extrapolation to a tapered wiggler experiment shows that power levels of 140 MW could be achieved with an efficiency of 7%.
