Abstract
We assume the presence of an initial light wave with wavelength λ l which may be provided either by an external source such as an optical laser, or by the spontaneously emitted undulator radiation which is captured in the optical cavity. Following the terminology in laser physics, one speaks of an FEL amplifier if the lasing process is initiated by seed radiation, and of an FEL oscillator if the lasing process starts from spontaneous radiation. The bunches make very many passages through the undulator.
