Abstract :
The TJNAF FEL can be upgraded to operate at 100 kW average power and then explore the use of a short Rayleigh length in order to reduce the power density on the resonator mirrors. The short Rayleigh length can only work with a relatively short undulator. Multimode simulations are used to self-consistently model the optical mode interaction with the electron beam. The steady-state resonator mode is affected by the complex, non-linear electron beam evolution as well as the resonator design.
