Patent
·
OSTI ID:6723005
This patent describes a method of suppressing feedback oscillations in a free electron laser having an elongated waveguide, means for providing an electron beam propagating through the waveguide, means for superimposing microwave energy onto the electron beam, and means for providing a wiggler field to provide an interaction region inside the waveguide. It comprises: placing an attenuator in the interaction region inside the waveguide.
