Scientists have utilized holographic projections to achieve unprecedented resolution in a light-based 3D printing technique.

< Exposure process: a USP laser writes a fiber Bragg grating into a fiber with a core diameter of 100 ... Fraunhofer ILT, Aachen, Germany / Volker Lannert.

New atomic clocks are more accurate than those used to define the second, suggesting the definition might need to change ...

The Laser Interferometer Gravitational-Wave Observatory, or LIGO, is one of the most powerful scientific equipment for detecting gravitational waves. Covering an area of 16 square kilometers, it also ...

The wacky, the wild, and the weird. E ven if you weren’t someone who got excited about science class in school, now—as an ...

Lightsails operate by harnessing radiation pressure from a light source, such as the Sun or lasers, to propel a spacecraft.

The best color laser printers are a great investment that can save you time and money compared to cartridge-based inkjet printers. Laser printers use toner, which lasts a long time, delivering a ...

That’s where lidar comes in. Like radar but using light, lidar sends beams from a plane or satellite toward the ground. By measuring the time it takes for the light to be reflected, scientists can ...

LISA is set to revolutionize our understanding of the gravitational universe and the interactions that make the entire cosmos ...

Photons have no mass, but they still transfer some of their momentum ... But a higher-energy version of this phenomenon could use a ground- or space-based laser beam to push a lightsail on a ...
