New research by scientists from the U.S. Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab), in collaboration with scientists from TAU Systems Inc., has brought the promise of ...

A technological milestone has been achieved at the Fritz Haber Institute (FHI) of the Max Planck Society in Berlin. For the first time, an infrared free-electron laser (FEL) has been operated in a two ...

Free-electron lasers (FELs) represent a transformative technology in the generation of coherent X-ray pulses that are both remarkably bright and ultrashort in duration. By utilising relativistic ...

Extremely intense light pulses generated by free-electron lasers (FELs) are versatile tools in research. Particularly in the X-ray range, they can be deployed to analyze the details of atomic ...

What are X-Ray Free-Electron Lasers? X-ray free-electron lasers (XFELs) are a revolutionary type of X-ray source that produce ultra-short, highly intense pulses of X-rays. Unlike conventional X-ray ...

Scientists have demonstrated a new method for generating and sustaining the high-quality electron beams required for X-ray lasers, a step toward making the instruments smaller and more affordable. The ...

Researchers from Germany, Japan and India, led by scientists from DESY and the Universities of Kiel and Hamburg, have found a way to collectively make molecules on a flat surface rotate by exposing ...

Scientists have revealed how lattice vibrations and spins talk to each other in a hybrid excitation known as an electromagnon. To achieve this, they used a unique combination of experiments on an ...

Relativistic electron bunches were generated via the incidence of a high power laser onto a gas jet. The TR radiation emitted when electron passing through a metal foil was imaged to an EO crystal.

A structured beam of electron beamlets (modulated group of white spheres) passes through a metallic foil from left to right creating coherent optical transition radiation (COTR). This radiation ...
