Abstract : The optical wavelength of a Free Electron Laser (FEL) is dependent on the input electron beam energy. So, as the energy of this beam varies, the optical wavelength from the laser will vary as well. In many applications, this effect may be unwanted and in others it may be desirable. At the Stanford University Superconducting Free Electron Laser Facility, a feedback mechanism has been implemented to study the effects of electron beam energy fluctuation. Here, numerical techniques are used to study optical wavelength modulation caused by electron beam energy modulation where the amplitude modulation is within the gain spectrum bandwidth of the FEl.
