Standing wave wigglers used in free-electron laser
Abstract
Operating conditions for free-electron lasers with a standing wave for wigglers are analyzed and the laser gains are calculated. A unique feature of free electron lasers is that the output wavelength can be tuned continuously by changing the energy of the relativistic electrons and the spatial period of the wiggler. In principle, output can be obtained in the infrared, ultraviolet, and even the X-ray range. A high energy relativistic electron beam is required to produce a short wavelength laser. Recently attempts have been made to obtain laser oscillation in the X-ray wavelength using free electron laser but great technical difficulties were encountered.
