Abstract
Computer simulation results reveal that the superradiant modes in free-electron laser amplifiers with high gain and long interaction length tend to degrade the amplifier performance. If these modes are kept at low levels, the amplifier efficiency can be significantly improved. This observation can be employed to interpret the recent MIT reversed guide field free-electron laser experiment.
