Abstract:

This patent discloses a free electron laser for use with a short-pulse relativistic electron source. The device includes a resonant optical cavity in which a spatially- periodic magnetic field is produced by a wiggle magnet assembly. An input optical beam having a wavelength lying within the gate bandwidth of the free electron laser interaction is injected into the cavity. A beam of relativistic electrons produced by a short-pulse source, such as an RF-linac, is injected into the cavity. The electron beam and the input optical beam interact under the influence of the magnetic field to amplify the input optical beam. JHD
