Free-electron lasers are particularly useful because they can produce radiation with a short-wavelength, down to just a few tenths of a nanometre. Thus, it is hoped they will become an important ...

Scientists have captured the moment a laser "comes to life"—and what they found challenges long-held beliefs. Using a special ...

Enrique Rico Ortega and Sofia Vallecorsa explain how quantum computing will allow physicists to model complex dynamics, from ...

DENVER, June 11, 2025--Xcimer Energy Inc. announced today that the inertial fusion startup has completed the world’s first electron-beam-pumped excimer laser funded by the private sector.

Xcimer Energy’s electron-beam-pumped excimer laser. Inertial fusion startup Xcimer Energy has announced it has completed what it calls the world’s first electron-beam-pumped excimer laser funded by ...

Using pulses of an ultrabright X-ray free-electron laser, the structure of liquid carbon was determined at pressures exceeding one million atmospheres and temperatures of around 7,000 kelvin. This ...

“Considering over six decades in laser development and tremendous challenges in translating many of the concepts to x-ray wavelengths, the realization of an attosecond atomic X-ray laser is a major ...

We propose a novel method for measuring relaxation rates and Fermi-contact fields of the electron and nuclear spin ensembles rapidly and synchronously in spin-exchange relaxation-free (SERF) atomic ...

We report spectroscopic measurements of the THz radiation generated by the free electron laser (FEL) FLARE using electron spin resonance at high magnetic fields, which show that the 150 micropulses ...

As the first magnetic Kagome material exhibiting charge density waves (CDWs), FeGe has garnered widespread research interest. In this work, we utilized low-temperature, high-magnetic-field scanning ...

Chiral plasmonic nanostructures possess a chiroptical response orders of magnitude stronger than that of natural biomolecular systems, making them highly promising for a wide range of biochemical, ...
