Revolutionizing satellite power using laser beaming

The University of Surrey and Space Power are tackling the problem of powering satellites in Low Earth Orbit (LEO) during their eclipse period when they cannot see the sun. By collaborating on a space infrastructure project, ...

A smarter way to make ultraviolet light beams

Existing coherent ultraviolet light sources are power hungry, bulky and expensive. University of Michigan researchers have found a better way to build compact ultraviolet sources with low power consumption that could improve ...

Inexpensive chip-based device may transform spectrometry

Spectrometers—devices that distinguish different wavelengths of light and are used to determine the chemical composition of everything from laboratory materials to distant stars—are large devices with six-figure price ...

Photonic quantum computers: A brighter future than ever

(Phys.org) —Harnessing the unique features of the quantum world promises a dramatic speed-up in information processing as compared to the fastest classical machines. Scientists from the Group of Philip Walther from the ...
