摘要

我们演示了用低电荷电子束(10pc)的非线性压缩产生持续时间低于1fs的相干软x射线自由电子激光(FEL)脉冲。该方法很简单，并且不需要任何特殊的硬件，因此可以在任何x射线FEL设施中轻松实现。我们提出了时间和光谱诊断，证实了光子能量为642和1111 eV的单尖峰亚飞秒脉冲的产生。我们的工作将对需要软x射线的超快FEL应用具有重要意义。

Coherent sub-femtosecond soft x-ray free-electron laser pulses with nonlinear compression

We demonstrate the generation of coherent soft x-ray free-electron laser (FEL) pulses with a duration below 1 fs using nonlinear compression with a low-charge electron beam (10 pC). The approach is simple, and it does not require any special hardware, so it can be readily implemented at any x-ray FEL facility. We present temporal and spectral diagnostics confirming the production of single-spike sub-femtosecond pulses for photon energies of 642 and 1111 eV. Our work will be important for ultrafast FEL applications requiring soft x-rays.
