Researchers have developed a new kind of lidar system that simultaneously measures the location, speed and material ...

Scientists at NPL have demonstrated the best-reported laser frequency stability achieved with an optical reference cavity operating at room temperature, marking a major advance in ultrastable laser ...

One of the hardest things to calculate for an asteroid is its mass—but it is such a critical feature. It determines how much ...

Navy laser wireless power beaming proved dual-purpose in a June 2026 field test: a single directed-energy platform beamed ...

The U.S. Naval Research Laboratory (NRL) has demonstrated a laser system that can both ...

Scientists have taken lasers beyond light and into the realm of sound, creating a breakthrough “phonon laser” that manipulates tiny vibrations at the quantum level. By dramatically reducing noise in ...

A practical look at common tape measure use on the job site, with a focus on accurate measuring and better building habits. What small measuring mistake do you see most often? Sisters charged with ...

High-energy lasers are spreading around the world. A new field known as counter-directed energy weapons could determine ...

In this work, we demonstrate a PIC-based Mamyshev oscillator MLL with erbium-doped silicon nitride waveguides. This system can be self-seeded and achieves a high pulse energy for a PIC-based MLL ...

For nanoscale X-ray imaging, scanning-based techniques are widely used, but the scanning process often becomes a bottleneck for measurement speed. Scanless, single-shot imaging provides a promising ...

How do you measure the inside of a cave? You could do a bunch of hard work with classic surveying gear… or you could just use a laser scanner. [9nl] did the latter, with a scanning rig of ...
