Abstract
Generalized conservation laws and gain-spread relations in the free-electron laser are derived for variable wiggler configurations. The derivation follows from the general equations of paper I in this series. It is suggested that bandwidth limitations on the optimization of the small-signal gain-to-spread ratio of a storage ring FEL might be overcome by transverse velocity filtering of the electrons.
