Abstract
An apparatus for producing high intensity laser radiation. A vacuum enclosure is provided which includes first and second magnets at each end, and a magnetic field applied along the length of the enclosure. The magnets and applied magnetic field forms a magnetic mirror for electrons of a near relativistic energies introduced into the vacuum enclosure. A thin dielectric material is provides which is charged on each side by some of the electrons which strike the surfaces of the dielectric. The charged dielectric provides high intensity electrostatic fields at the edges thereof. The strength of the magnets and applied magnetic field are selected to produce an oscillation of electrons which pass through the high intensity electrostatic fields and are subject to a radial acceleration which produces free electron lasing. The laser energy is collected by an optical cavity within the enclosure. The laser energy exits an optical port within the enclosure.
