Laser

Scientists have demonstrated a novel approach to tackling arterial plaque that relies on laser, ultrasound and exploding microbubbles to destroy it with greater safety and efficiency, while hinting at unique long-term advantages.

A team of Harvard engineers working to advance laser technology have turned to one of the strongest known materials in diamonds, which they've used to form a new mirror that can endure beams strong enough to burn through steel.

Teledyne FLIR Defense has developed a multi-role laser designator called the StormCaster-DX. The military targeting system can be attached to a quadcopter small and light enough to be carried in a soldier's rucksack.

Researchers have now developed the fastest logic gates ever created, by zapping graphene and gold with laser pulses. The new logic gates are a million times faster than those in existing computers, demonstrating the viability of “lightwave electronics.”

The world’s most powerful X-ray laser is ready for operation after a massive overhaul. The upgraded LCLS-II uses temperatures colder than deep space to accelerate electrons to near light-speed and fire off a million X-ray bursts per second.

When most people think of 3D printing, they likely picture a relatively chunky object being built one layer at a time. A new technique, however, allows much more intricate items to be produced – and it does so by changing the color of laser light.

While it may not rate way up there on a list of life's annoyances, measuring a child's height in the traditional wall-marking fashion can be a tad fiddly. That's where the Kiko comes in, as it uses a laser to do the job quickly and easily.

Robots and other automated systems have always had trouble visually gauging the 3D shape of transparent objects, like those made of glass. A new system addresses that problem, by using a laser to quickly heat such items.

A team of European researchers has suggested that the Moon’s orbit could be used as a gigantic detector for gravitational waves. These waves, much smaller than those that existing detectors can pick up, could originate from the early universe.

Researchers have demonstrated key tech that could help scale up quantum computers, creating a model with a record-breaking 512 qubits. The team combined atoms of two elements into an array, so atoms can be manipulated without disturbing their neighbors.

Radio waves don't travel well through water, which is why devices such as ROVS have to be linked to their operator via a communications cable. According to a new study, however, solar panels may soon allow for practical light-based communications.

Epson has introduced what's billed as its most advanced home theater projector to date. The LS12000 combines a new light source with processing algorithms and some nifty pixel-shifting technology to deliver a "zero compromise" 4K image on the wall.
