The Advanc d Free Electron Laser (AFEL) is a coinpact, infrared, rf-linac FEL that uses a high-brightness photoinjector and a short-period permanent-magnet wiggler. Lasing at saturation with and without sidebands has been achieved over the 4-6 pm region with a nominally 15-MeV electron beam energy and a l-cmperiod, 24-period wiggler. Sideband-free FEL operation was optimized with respect to outcoupling by tuning off the reflectivity curve of ihe multilayer dielectric mirrors. Sidebal,d operation was achieved using copper mirrors with a 1.170 outcoupling hole. The measured macropulse energy with -1300 micropulses was approximately 50 mJ per 1 nC of beam, corresponding to an output efficiency of 0.25% and a maximum extraction efficiency of 1.4%.
