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 ...

MENLO PARK, Calif. (KGO) -- The world's most powerful X-ray laser is located at the SLAC National Accelerator Laboratory in the Bay Area, and it's about to become even more powerful. According to Mike ...

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 ...

Researchers at the European XFEL have made major progress in understanding how light interacts with matter at the quantum level after they achieved a 100-fold boost in photoionization efficiency. The ...

Scientists have used a pair of lasers and a supersonic sheet of gas to accelerate electrons to high energies in less than a ...
