Postsaturation dynamics and superluminal propagation of a superradiant spike in a free-electron laser amplifier
We study the dynamics of an isolated spike of radiation in superradiant regime. We show that conditions exist where the pulse moves with a group velocity larger than the velocity of light in vacuum and is followed by a pedestal resulting from a complex postsaturation dynamics. The tail is constitute...
