Abstract
Free electron laser apparatus, for producing coherent electromagnetic radiation within a spectral range extending from millimeter to visible wavelengths, includes elements for generating an electron beam and for directing the beam to move over the surface of a diffraction grating, thereby producing electromagnetic radiation. Optical or quasi-optical elements confine the electromagnetic radiation to generate feedback, resulting in stimulated, coherent emission.
