Fully coherent short wavelength free-electron laser driven by a single sub-microjoule seed
Lanpeng Ni, Zheng Qi, Xingtao Wang +33
High-repetition-rate, fully coherent extreme-ultraviolet (EUV) and X-ray free-electron lasers (FELs) are essential for advanced time-resolved ultrafast spectroscopies. While extern…
