ViewSonic has announced a new compact projector called the M10 that features a triple laser light source, offers Full HD visuals with support for HDR/HLG content, and comes with built-in Harman Kardon sound.

Researchers have developed a handheld device that shines a safe laser into the eye to detect biomarkers of brain damage following a concussion or other traumatic brain injury, providing rapid, on-site diagnosis at the time of injury.

The USA has only two accelerators that can produce 10 billion electron-volt particle beams, and they're each about 1.9 miles long. "We can now reach those energies in 10 cm," said the CEO of TAU Systems, which has built an ultra-compact accelerator.

NASA's Deep Space Optical Communications (DSOC) unit aboard the Psyche spacecraft has switched on, establishing a super-speed laser data link at a distance of 10 million miles (16 million km), or 40 times the distance from the Earth to the Moon.

A team of researchers led by the University of Cambridge has developed a new technique that uses high-energy lasers to fine tune the properties of 3D-printed metal without compromising the complex shapes it forms.

NASA will soon demonstrate a laser-based communication system between ground facilities and the International Space Station. The technology will boost data transmission speeds by 10 to 100 times, potentially opening a new standard in deep space comms.

Gravitational wave facilities measure spacetime distortions down to 10 quadrillionths of a hair – small enough for interference from particles popping in and out of existence. Now LIGO has pushed beyond this quantum limit by “squeezing” laser light.

The Moon is a dusty place, so to tidy things up a bit, ESA is experimenting with high-energy lasers and simulated lunar soil to explore the possibility of sintering lunar regolith to pave roads and landing fields for future lunar outposts.

Sharp/NEC Display Solutions in Europe has launched a 14,000-lumen laser projector that's pitched as an ideal replacement for current models using Xenon lamps in small booth theaters or boothless mobile cinema setups.

Guiding lasers where they need to go is a key part of optics systems, and now engineers at DESY have developed a way to bend laser beams without anything touching them. The light is deflected using an invisible grating made of air shaped by acoustics.

The Royal Swedish Academy of Science has awarded the 2023 Nobel Prize in Physics to Pierre Agostini, Ferenc Krausz and Anne L'Huillier for work that's "given humanity new tools for exploring the world of electrons inside atoms and molecules."

The SLAC National Accelerator Laboratory has switched on the world's most powerful X-ray laser. The Linac Coherent Light Source II X-ray Free-Electron Laser (XFEL) flashes a million times a minute and is 10,000 times brighter than its predecessor.
