摘要：

We derive a formula for the free-electron laser gain in the small-signal, low-gain regime which resembles closely the 1-D formula but taking into account the effect of wave diffraction, and electron beam divergence and betatron motion. The formula is cast in a form which exhibits clearly the role of the transverse phase space distribution of photons and electrons.
