What "Star Wars" laser bolts would actually look like

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

Reversible tractor beam can repel and attract objects

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.Read More

NIST's new laser technology allows high-definition 3D mapping at a distance

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

Researchers achieve long-distance light to matter quantum teleportation

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

Turret flight tests to pave the way for laser weapons on military aircraft

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

NASA probe will reveal 3D architecture of forests from space

NASA is developing a laser-based instrument for deployment on the International Space Station that will probe the depths of Earth's forests from space in a bid to reveal more about their role in the planet's carbon cycle. After its completion in 2018, this Global Ecosystem Dynamics Investigation (GEDI) lidar will join the likes of the Soil Moisture Active Passive satellite in studying Earth's vegetation on a global scale.Read More

Neither rain, nor fog, nor wind stops Boeing's laser weapon destroying targets

If you've ever gone outside on a foggy night and shined a laser pointer about, you’ve seen two things: how flashy a raygun it makes, and the problem laser weapons face in such conditions as fog and rain scatters the energy that should be destroying missiles. However, in recent tests at Eglin Air Force Base in Florida, Boeing and the US Army have shown that their High Energy Laser Mobile Demonstrator (HEL MD) is capable of successfully locking onto and taking out targets in very laser-unfriendly foggy, rainy, and windy maritime conditions.Read More

Fermilab experiment will attempt to answer whether we actually live in "the Matrix"

In what may be one of the most mind-bogglingly surreal experiments ever floated, scientists at the US Department of Energy's Fermi National Accelerator Laboratory (Fermilab) will attempt to discover if the universe is "real" or merely a holographic 3-D illusion that we just think is real. Using high-powered lasers, the scientists intend to determine if space-time is a quantum system made up of countless tiny bits of information.Read More
