摘要：

We continue the study of the hole-coupling resonator for free-electron laser (FEL) applications. The previous resonator code is further developed to include the effects of the azimuthally asymmetric modes and the FEL gain. The implication of the additional higher-order modes is that there are more degeneracies to be avoided in tuning the FEL wavelengths. The FEL interaction is modeled by constructing a transfer map in the small-signal regime and incorporating it into the resonator code. The FEL gain is found to be very effective in selecting a dominant mode from the azimuthally symmetric class of modes. Schemes for broad-wavelength tuning based on passive mode control via adjustable apertures are discussed.
