Coherent dynamics of a free-electron laser with arbitrary magnet geometry. II. Conservation laws, small-signal theory, and gain-spread relations Academic Article uri icon


  • 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. 1980 The American Physical Society.
