摘要：
The CEA/CESTA free-electron laser amplifier has been operated in the self-amplified spontaneous emission mode. This waveguide laser has two resonant frequencies for given beam energy and wiggler held, at approximately 3 and 35 GHz, respectively, for our operating conditions. Highly reproducible microwave power levels of 40 MW and pronounced electron bunching are seen at the lower frequency. Streak camera photographs of the time dependence of the bunching mechanism at the lower frequency are presented. The bunching is accompanied by a significant loss of electrons from the beam.
