The energy sent is low-intensity, invisible infrared light, which allows ground-based solar projects to generate power even when the sun is not shining. Unlike other concepts, Overview’s wide-beam ...

Laser beam incident on the structured droplet sets up plasma waves (blue pulses) that accelerates electrons (green solid spheres) to megaelectronvolt energies. In massive particle accelerators, ...

Intense, extremely short-wave X-ray pulses in the nanometer wavelength range are difficult to produce, but now a new, simpler method has been developed at TU Wien (Technical University of Vienna, ...

Researchers at the University of Maryland (UMD) have demonstrated a continuously operating optical fiber made of thin air. The most common optical fibers are strands of glass that tightly confine ...

In a step toward making ultra-bright X-ray sources more widely available, an international collaboration led by the University of Michigan—with experiments at the U.K.'s Central Laser Facility—has ...

The DragonFire laser directed-energy weapon achieved the U.K.’s first high-power firing of the weapon type against an aerial target. (Photo provided/British Defence Ministry) (THE CONVERSATION) ...
