Abstract
We present evidence of stochastic resonance in free-electron lasers. In order to do that, we have analyzed theoretically the dynamics of a free-electron laser oscillator. A weak modulation and a noise source have been applied to the initial energy of the electron beam. We have found stochastic resonance for different frequencies and amplitudes of the modulation. A threshold crossing mechanism leads to the stochastic resonance in this system.
