ABSTRACT:
A technique for constructing electromagnetic oscillators and amplifiers producing coherent radiation tunable from the microwave through the x-ray spectral regions. The resulting class of devices posses such novel and desirable features as broad band or narrow band operational capability in a high power and high efficiency mode. A relativistic electron beam is injected into an axial solenoidal magnetic field with a component of perpendicular motion and subsequently rotates and emits synchrotron radiation. Radiation of the proper frequency and direction will pass over the rotating beam electrons in such fashion as to cause them to lose energy to the radiation field and thus cause the intensity of the radiation field to increase. Selection of the proper radiation cavity results in laser oscillator or amplifier behavior with novel attributes.
