Since 2013 the FHI Free-Electron Laser (FHI FEL) provides intense, pulsed mid-infrared (MIR) radiation continuously tunable from 2.8 to 50 micron wavelength. The generation of molecular vibrational ...
A single gold nanorod, far smaller than a wavelength of visible light, can be coaxed into emitting circularly polarized radiation simply by nudging the electron beam that excites it a few nanometers ...
