Intensity saturation mechanism in free electron lasers

Technical Report:

Abstract

The gain saturation mechanism of a free electron laser (FEL) is different from that of a conventional laser. Furthermore, the interaction itself causes an energy loss of the electron beam and induces an energy spread, thus determining the saturation of the system itself. Albeit apparently different, the FEL gain saturation mechanism is reproduced by an equation analogous to that exploited for conventional lasers. This paper proves that the FEL exhibits a scaling of the gain saturation versus intensity which is analogous to that of conventional lasers; introduces the concept of FEL intensity of saturation and finds its expression in terms of the system parameters; and finds a simple relationship between FEL output intensity and saturation intensity.
