Why it matters
Analysis / 分析: Achieving attosecond X-ray pulses enables unprecedented observation of ultrafast electron dynamics, which could drive advancements in materials science and quantum device characterization.
X-ray Free-Electron Laser Sets New Record for Shortest High-Energy Pulses
Researchers at SLAC's Linac Coherent Light Source (LCLS) have measured the shortest high-energy X-ray pulses ever recorded at an XFEL. The pulses, with photon energies of about 9 keV, lasted only 100 to 400 attoseconds, a result published in Nature Photonics.
