New lens system for brighter, sharper diffraction images

To design and improve energy storage materials, smart devices, and many more technologies, researchers need to understand their hidden structure and chemistry. Advanced research techniques, such as ultra-fast electron diffraction ...

Cooling with light

ETH researchers have cooled a nanoparticle to a record low temperature, thanks to a sophisticated experimental set-up that uses scattered laser light for cooling. Until now, no one has ever cooled a nanoparticle to such ...

Peering into plasma mirrors

When light interacts with a mirror which is moving towards it at a speed close to the speed of light, its wavelength is shifted into the extreme ultraviolet region of the spectrum. This effect was first predicted by Albert ...

Quality of laser beam shaping can be enhanced at no extra cost

Researchers from Osaka University have developed a technique for improving accuracy of laser beam shaping and wavefront obtained by conventional methods with no additional cost by optimizing virtual phase grating. The results ...

Nanocomponent is a quantum leap for Danish physicists

University of Copenhagen researchers have developed a nanocomponent that emits light particles carrying quantum information. Less than one-tenth the width of a human hair, the miniscule component makes it possible to scale ...

Breakthrough research to revolutionise internet communication

A team of University of Otago/Dodd-Walls Centre scientists have created a novel device that could enable the next generation of faster, more energy efficient internet. Their breakthrough results have been published in the ...

Tuning terahertz transmission

The ability to manipulate light on a subwavelength-scale could lead to a revolution in photonic devices such as antennas, solar panels, and even cloaking devices. Nanotechnology advances have made this possible through the ...

Researchers develop the next generation of endoscopy technology

Biotechnologists, physicists, and medical researchers at Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU) have developed technology for microscopic imaging in living organisms. A miniaturised multi-photon microscope, ...

New method to create ultrafast 3-D images of nanostructures

Lensless microscopy with X-rays, or coherent diffractive imaging, is a promising approach. It allows researchers to analyse complex three-dimensional structures, which frequently exist in nature, from a dynamic perspective. ...

New super-accurate optical atomic clocks pass critical test

Researchers have measured an optical clock's ticking with record-breaking accuracy while also showing the clock can be operated with unprecedented consistency. These achievements represent a significant step toward demonstrating ...
