利用两束激光脉冲相互作用，将等离子体电子注入其中一束激光脉冲激发的韦克菲尔德，产生了高质量强流相对论电子束。从理论上分析了注入的机理，并通过数值模拟验证了高质量电子束的产生。电子束的能散小于1%，超短脉冲宽度小于10 fs，归一化横向发射度小于1 π mm mrad。
High quality intense relativistic electron beams are generated by the interaction of two colliding laser pulses to inject plasma electrons into a wakefield excited by one of the laser pulses. The mechanism of the injection is analyzed theoretically and the generation of a high quality electron beam is verified by the numerical simulation. An electron beam has a small energy spread of 1%, ultrashort pulse duration less than 10 fs and normalized transverse emittance less than 1 π mm mrad.
