自由电子激光器（FEL）几乎可以在从微波到紫外线的整个电磁波谱上工作，平均功率高达2kW。需要在注入器技术方面取得进展，以在更短的波长（如X射线）或更高的平均功率下工作。这可以使用多个注入器并组合光束来实现。初步模拟这一概念已被应用到拟议的设计的1.5直线加速器相干光源。空间电荷和相干同步辐射对合束物理的影响的局限性有待进一步研究。
Free-electron Lasers (FELs) have operated over virtually the entire electromagnetic spectrum from microwaves through the ultraviolet and up to average power levels of 2kW. Advances in injector technology are needed to operate at shorter wavelengths, such as X-rays, or higher average powers. This can be achieved using multiple injectors and combining the beams. Initial simulations of this concept have been applied to the proposed design of the 1.5Å Linac Coherent Light Source. Further studies will be conducted on the limitations of the effects of space-charge and coherent synchrotron radiation on the physics of combining beams.
