Photon statistics of a free-electron laser

Journal Article · · Phys. Rev. A; (United States)
A fully quantized theory of the free-electron laser in the small-signal regime is presented which allows for a calculation of the photon statistics. For an initial vacuum, we find photon antibunching if the electron momentum is below resonance. We conjecture that in general the free-electron laser preserves coherent states only in the absence of gain.
