Coherent Light with Tunable Polarization from Single-Pass Free-Electron Lasers
Coherent Light with Tunable Polarization from Single-Pass Free-Electron Lasers
Tunable polarization over a wide spectral range is a required feature of light sources employed to investigate the properties of local symmetry in matter. In this Letter, we provide the first experimental characterization of the polarization of the harmonic light produced by a free-electron laser and demonstrate a method to …
