本文介绍了用单能电子束实现的宽带双色自由电子激光放大器的研究。双色自由电子激光的相互作用是使用一系列的波荡器模块交替调谐到两个良好分离的谐振频率。使用宽带自由电子激光模拟程序Puffin，电子束在两个谐振频率下同时发生强烈的聚束。在谐振频率的和与差处也产生电子聚束分量。
Studies of a broad bandwidth, two-colour free electron laser (FEL) amplifier using one monoenergetic electron beam are presented. The two-colour FEL interaction is achieved using a series of undulator modules alternately tuned to two well-separated resonant frequencies. Using the broad bandwidth FEL simulation code Puffin, the electron beam is shown to bunch strongly and simultaneously at the two resonant frequencies. Electron bunching components are also generated at the sum and difference of the resonant frequencies.
