Abstract
In a two-stage FEL long wavelength (~100-1000 µm) radiation is produced using a wiggler magnet. The long wavelength radiation then serves as the pump field to produce short wavelength (~1-10 µm) radiation by scattering from a low energy (~3 MeV) electron beam. To obtain the very high pump field intensities (~ 107-109 w/cm2) required for this application, the long wavelength radiation must be contained in a low loss resonant cavity. A long narrow interaction region is needed in which the electron beam can interact with the high intensity pump field, but the pump beam diameter must be large at the cavity end mirrors to prevent mirror damage. A quasioptical cavity ...
