ABSTRACT:
The disclosure relates to an undulator, namely a device generating a transverse magnetic field polarized alternatively North-South and South-North along the path of an electron beam and enabling the direct conversion, in a free electron laser, of a part of the energy of a beam of relativistic electrons into light energy. The undulator comprises a conductor forming, along the path of the electron beam, undulations that wholly or partially induce the transverse magnetic field. To increase the light efficiency, it consists in providing for auxiliary current bypass connectors on said conductor. These auxiliary connectors enable the modulation of the transverse magnetic field as a function of the changing characteristics of the high frequency electrical field which increases during the arrival of a packet of electrons in the optical cavity of the laser owing to the energy yielded by these electrons.
