摘要
本文提出一种可以工作在软X射线区的用孤子激光抽运的新型自由电子激光器,利用孤立子激光的波型以及单粒子小信号分析方法,发现这种自由电子激光具有以下两个不同于以往电磁波振荡器自由电子激光的特点: (1)很小的“质量漂移效应”(mass-shift effect),这是由孤立子激光抽运的特征所决定; (2)具有一个附加的“频率调谐性”,即可展宽自由电子激光的频率调谐能力。 对获得的小信号增益也进行了一些分析和讨论。
We propose a scheme of building a free-electron laser in the soft X-ray region pumped by the soliton laser. Making use of soliton laser wave evolution shape and single-pass small signal analysis, we find that this laser has two special advantages over the previous electromagnetic wave undulator free-electron lasers namely, (1) a very small 'mass-shift effect' because of the special characteristics of soliton lasers, (2) an additional 'frequency tuning effect' based on the conventional free-electron laser's tuning ability. We also obtain the small signal gain and carry out some discussion.
