摘要：
The Los Alamos compact Advanced Free Electron Laser (AFEL) has lased at 4.7 and 5.2 mum with a 1-cm period wiggler and a high-brightness electron beam at 16.8 and 15.8 MeV, respectively. The measured electron beam normalized emittance is 1.3 pi mm mrad at a peak current of 100 A, corresponding to a beam brightness greater than 2 X 10(12) A/m2rad2. Initial results indicate that the AFEL small signal gain is approximately 8% at 0.3 nC (30 A peak). The maximum output energy is 7 mJ over a 2-mus macropulse. The AFEL performance can be significantly enhanced by improvements in the rf and drive laser stability.
