Ultra-fast switching of helicity of circularly polarized light pulses
The ultra-fast change of light helicity is particularly interesting to observe processes in magnetic materials
03-Apr-2020 -
At the BESSY II storage ring, a joint team of accelerator physicists, undulator experts and experimenters has shown how the helicity of circularly polarized synchrotron radiation can be switched faster - up to a million times faster than before. They used an elliptical double-undulator developed ...
