The introduction of a strongly magnetized plasma in the inner region of a Free Electron Laser opens up the possibility of generating coherent radiation in the slow whistler mode using mildly relativistic electron beams. The frequency of emission, however, is limited to below the electron cyclotron frequency. The efficiency of the device can be enhanced by tapering the guide magnetic field.
