<p>An SOR light generating apparatus in which an SOR light generated from the charged particles circulating along a circular orbit in the form of a bunch at speeds close to the speed of light, is reflected by a reflector which is so arranged as to surround the circumference of the orbit in order to accumulate the SOR light in the reflector and to guide it to a light take-out port. Using a reflector having a curvature with which the reflected SOR light comes into contact with the orbit of the charged particles, the SOR light generated at a contact point is guided to the light take-out port along the light path same as the reflected SOR light. Therefore, efficiency for utilizing the SOR light is markedly improved. Further, the SOR light generated from a given bunch is reflected and is permitted to be incident on another bunch and, moreover, the SOR light emitted from the head of a given bunch is permitted to be incident on the tail portion of the same bunch, in order to obtain a short pulse having a large strength. By causing the SOR lights from the bunches and the reflected SOR lights to be interfered by each other, it is possible to obtain a monochromatic SOR light. Laser oscillation can also be effected by disposing a diffraction grating on at least a portion of the reflector to select a wavelength of SOR light or by projecting a laser beam from an external unit.</p> |
