The city of Vienna has hosted a laser light show with a twist with University of Vienna scientists having tested a new way of transmitting data over a light beam. The technique, which exploits classical and quantum mechanics, promises to provide the ability to send much more information through the air much more securely. Read More
Drones cruising through Chinese airspace may be set for rude awakening, with local scientists reportedly developing a laser capable of shooting the vehicles out of the sky. Chinese media are reporting that researchers from the China Academy of Engineering Physics have been working on a laser defense system to safeguard against the proliferating technology, and its early testing has been largely viewed as a success.

Russian scientists have proposed a novel way to accelerate a spaceship while in flight – firing a ground-based laser up its backside. The new technique uses a plasma flow caused by laser ablation to increase the exhaust efficiency of a traditional rocket propulsion system, and could theoretically accelerate an aircraft beyond Mach 10.

It's no secret that Star Wars is full of scenes that defy the laws of physics. From space battles inspired by WW I and II dogfights to beams of light clashing in lightsaber duels. The laser bolts fired from Han Solo's trusty blaster and Luke's X-wing also play by their own rules, traveling much slower than the speed of light and being perfectly visible in the vacuum of space. Researchers in Poland have now created a film to show what a laser bolt would actually look like. Read More
We're still a far cry from Star Trek's ship-towing and repelling technology, but laser physicists at the Australian National University (ANU) have built a tractor beam that can repel and attract objects. The beam moved spherical glass shells one fifth of a millimeter in diameter across a distance of up to 20 centimeters (7.87 in), which is around 100 times further than previous experiments at this scale, using only a single hollow laser beam that's bright around the edges and dark in its center.

Using an enhanced LADAR (Laser Detection And Ranging) system, researchers at the National Institute of Standards and Technology (NIST) have created a long-range, laser-based imaging device that can generate high-definition 3D maps of objects at distances of up to 10.5 m (35 ft). The technology could find applications in precision machining and assembly, as well as in forensics where it could map evidence non-destructively. Read More
When I covered MakerCon last month in New York for Gizmag, literally one of the first things I did was text a photo of the 45-lb (20 kg), tote-able laser cutter to my friend who owns a shop back home in New Mexico. As it turns out, that's exactly the type of consumer Pittsburgh startup Red Ant hopes to target with its Origami. Read More
By now, many regular Gizmag readers will be familiar with German cyberpunk weapons-hobbyist Patrick Priebe. We've featured a number of his one-off DIY creations before, including an Iron Man-inspired laser gauntlet. Well, now he's created another Iron Man gauntlet, although instead of just a burning laser, this one launches real rockets – and Priebe has already managed to hurt himself with the thing. Read More
A successful test in passing information from light into matter – using the teleportation of the quantum state of a photon via optical fiber cable to a receiving crystal located over 25 km (15 mi) away – has been claimed by physicists at the University of Geneva. This test shattered the same team’s previous record and may herald the development of greater, long-distance teleportation techniques and qubit communications and computing capabilities. Read More
High energy laser (HEL) systems have been the subject of military research for decades, but it is only in recent years that the technology has advanced to the point where it is feasible for such systems to be mounted on military ground vehicles and sea vessels. Initial flight tests have now been conducted on a new aircraft laser turret that will help pave the way for HEL systems to be integrated into military aircraft. Read More
