A team led by scientists at the Department of Energy's SLAC National Accelerator Laboratory have generated a highly exotic type of light beam, called a Poincaré beam, using the FERMI free-electron ...

With dual lasers, researchers have accelerated a high-quality beam of electrons to 10 billion electronvolts in just 30 centimeters. The experiment gives scientists a 'frame-by-frame' look at how a ...

A team of engineers and scientists has shown for the first time that a hard-X-ray cavity can provide net X-ray gain, with X-ray pulses being circulated between crystal mirrors and amplified in the ...

Since the 1980s, researchers have sought to use laser light to control chemical reactions relevant to photochemistry, ...

Lasing is much more difficult at X-ray frequencies than with visible light. The conditions that enable electrons in an atom to stay at sufficiently high energy levels to produce an X-ray laser cannot ...
