Abstract
Within a vacuum vessel,there are arranged an electron gun,emitting an electron beam and an amplification part,which amplifies incident light,by means of the energy of the electron beam. The amplification part,is formed by two wave-like mirrors,and,made of a metal such as Ag or a multi-layer structure of dielectric materials, said mirrors being separated from each other to constitute not only an electron beam travelling part, but also a light input part,a light amplifying part,and a light output part,arranged in this order viewed in a travelling direction of the electron beam. The light is made incident upon the light input part at a given incident angle, and propagates along the wave-like or zigzag optical waveguide within the light amplifying part by repeating reflections. Therefore, the wavenumber of the light is increased, and the light is amplified in a unidirectional manner by the energy of the electron beam. The thus amplified light emanates from the light output part at a given exit angle.
