A STIMULATED TRANSITION RADIATION OPTICAL KLYSTRON
受激渡越辐射光学速调管

A new scheme of an optical klystron based on stimulated transition radiation is proposed.Calculations on spontaneous and stimulated emission are made for such a device using Madey's theorem in free electron lasers (FEL). The analysis in this paper shows that Madey's theoremcan really simplify the calculations and give clear physical concepts. The case of N mediumsections cascaded through magnetic field dispersive sections is also discussed.
