The sideband instability in free electron laser oscillators: Effects of tapering and electron energy spread
Abstract
We consider the effects of a finite electron energy spread and of a tapered undulator on the optical mode evolution in free electron laser oscillators. We find that the sideband instability at high optical powers for monoenergetic, untapered cases is suppressed by tapering but not by an energy spread. We explain these results in terms of the synchrotron oscillations of the electrons.
