Dynamic cavity desynchronization in a shout pulse free-electron laser resonator

초록

It is well known that the cavity detuning length is one of the most important parameters in free-electron laser (FEL) oscillators, especially for operating with short electron pulses. Using one-dimensional Maxwell-Lorentz coupled equations, we demonstrate the control of short-pulse FEL oscillator characteristics by changing dynamically the effective cavity detuning length. The optimal operation conditions of the dynamic cavity desynchronization (DCD) scheme are thoroughly investigated by an extensive simulation work.
