Self-Synchronized Terahertz and X-Ray Free-Electron Lasers from a Single Pre-Bunched Electron Beam
Yin Kang, Kaiqing Zhang, Zhen Wang +27
Ultrafast pump-probe spectroscopy combining intense terahertz (THz) and X-ray pulses is a critical tool for investigating complex structural and electronic dynamics in materials. H…
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…
Demonstration of High-Gain Harmonic Lasing in a Terahertz Free-Electron Laser
Yin Kang, Cheng Yu, Yue Wang +26
Compact Free-Electron Lasers (FELs) offering broad, continuous spectral tunability are traditionally constrained by fixed-parameter magnetic structures and the necessity for high-e…
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…
Enabling Continuous THz Band Coverage via Precise Electron Beam Tailoring in Free-electron Lasers
Yin Kang, Tong Li, Zhen Wang +28
High-power, continuously tunable narrowband terahertz (THz) sources are essential for advancing nonlinear optics, THz-driven material dynamics, and ultrafast spectroscopy. Conventi…
