Researchers contributed to a deeper understanding of free electron laser physics by evaluating the interaction between an ultraviolet laser and a relativistic electron beam in a pure dipole magnet.

The electron-phonon coupling intensity is calculated by Huang-Rhys S factor and the phonon-assisted fluorescence lineshape is predicted numerically. A broadband lasing emission spectrum (1000-1280 nm) ...

Free electron lasers (FELs) generate short-wavelength radiation with extreme brilliance on ultrafast timescales. Developed over the past three decades, FELs provide an important research tool for ...

Electron and phonon are two fundamental particles (quasi-particles) of condensed matter and their interplay in single crystals can create many interesting physical phenomena, such as polariton, charge ...
