摘　　要：自从20世纪70年代在斯坦福大学构思并演示了第一个自由电子激光器(FEL)以来,其作为一种高平均功率光源而受到广泛关注。FEL的光是由自由电子产生的,所以可被设计成几乎任何波长的激光,此外,其增益介质不会被任何传统的方法破坏。因此,在过去的几十年里,已经出现了一些雄心勃勃的尝试以设计和构建高平均功率FEL。文中提供了一个关于FEL原理的概述,总结了其关键技术及军事方面的研究,并对其未来发展进行展望。Ever since the first free-electron laser(FEL)is both conceived and demonstrated in the 1970s at Stanford,it has attracted much attention as a high average power light source.Since its light is produced from free electrons,an FEL can be designed to laser at virtually any wavelength.Furthermore,its gain medium cannot be damaged by any conventional means.Accordingly,as there have been several ambitious attempts to design and construct high average power FELs over the past several decades.Additionally,an overview of FEL theory is provided,the key techniques and research in the military are summarized,and the future development is prospected.
