Phase-Stable Self-Modulation for GHz Continuous-Wave Ultrafast X-Ray Free-Electron Lasers
Junhao Liu, Zhen Wang, Lanpeng Ni +3
High-brightness femtosecond-to-attosecond pulses are indispensable for probing electron dynamics on their fundamental temporal scales. X-ray free-electron lasers (XFELs) at high re…
Lattice design of a storage-ring-based light source for generating high-power fully coherent EUV radiation
Yujie Lu, Ao Liu, Changliang Li +10
We present the physical design and systematic optimization of a high-performance storage ring tailored for the generation of high-power coherent radiation, with particular emphasis…
Attosecond Waveform Synthesis through Echo-enabled Harmonic Generation Free-electron Lasers
Lanpeng Ni, Junhao Liu, Zheng Qi +1
Attosecond pulse trains (APTs) are indispensable for probing electron dynamics at their intrinsic timescales. High harmonic generation (HHG) has long been a successful and widely u…
First Lasing and Stable Operation of a Direct-Amplification Enabled Harmonic Generation Free-Electron laser
Zheng Qi, Junhao Liu, Lanpeng Ni +27
Seeded free-electron lasers (FELs) capable of operating at repetition rates up to the MHz level are in high demand for advanced time-resolved spectroscopies, which require both ful…
