A static periodic field device for a free electron laser has a plurality of holes there through to allow the interaction of electrons flowing there through to interact with either an electric or a magnetic fields as desired. The device is composed of a plurality of conducting layers separated by insulating layers and appropriately connected to provide either an electric or a magnetic field therein. Th separation of the conducting layers determines the radiated energy wavelength. Patent applications. jhd
