Effects producing gain dilution in Free Electron Laser devices are well documented. We develop here a unified point of view allowing the introduction of space charge effects, along with the gain deterioration due to inhomogeneous broadening contributions and discuss the relevant interplay. We outline future developments and comment on the possibility of including in the formalism effects of quantum mechanical nature.

自由电子激光演化中的空间电荷和量子校正

在自由电子激光设备中产生增益稀释的效应已得到充分证明。我们在这里提出一种统一的观点，允许引入空间电荷效应，以及由于不均匀的扩展贡献而导致的增益衰减，并讨论相关的相互作用。我们概述了未来的发展，并评论了将量子力学性质纳入形式主义效应的可能性。
