Laser

A research team at Singapore’s Nanyang Technological University (NTU) has successfully used a laser to cool down a semiconductor material known as Cadmium Sulfide. The results of the recently published study could lead to the development of self-cooling computer chips and smaller, more energy efficient air conditioners and refrigerators that don't produce greenhouse gases.

When someone mentions counterfeiting, it brings up images of money, watches or DVDs. It certainly doesn't make honey spring to mind, yet honey smuggling and counterfeiting is an international problem involving hundreds of millions of dollars. In an effort to combat this, the European Space Agency (ESA) is funding a demonstration project to adopt lasers designed to study the Martian atmosphere, to detect fake honey. Read More
While walking through CES 2013, we happened upon something intriguing from JVC Kenwood. The company had a prototype laser heads-up display (HUD) on the floor that sports some interesting features, and that could soon show up as standard equipment on a variety of automobiles. Read More
From The Skylark of Space to Star Wars, no self-respecting science fiction spaceship would break orbit without a tractor beam on board. We’re still a long way from locking on to errant shuttlecraft, but a team led by Dr. Tomas Cizmar, Research Fellow in the School of Medicine at the University of St. Andrews, Scotland, has turned a laser into a tractor beam that works on the microscopic level.

Given that most real-life superheroes don’t have the budget of Tony Stark or Bruce Wayne, you would assume that their gadgetry wouldn’t be quite on par with what we’re used to seeing in the movies. German cyber weapons hobbyist Patrick Priebe recently dropped us a line, however, to tell us about his latest homebuilt creation – a working laser gauntlet, just like the one made famous by a certain Iron Man.

Barrett’s esophagus is a precancerous condition typically caused by chronic exposure to stomach acid, and is usually diagnosed by inserting an endoscope down the patient’s throat. A tool has been developed, however, that should allow for a quicker, easier way of getting a good look at such peoples’ esophagus – it’s a swallowable capsule that contains a spinning laser.

Practical high-energy laser weapons came a step closer to reality in November as Rheinmetall tested its new 50 kW high-energy weapon laser demonstrator. The series of exercises took place at the German-based group’s Ochsenboden Proving Ground in Switzerland. There the 50 kW laser weapon was tested against a series of targets to show the improvements over last year’s 10 kW version. Read More
Engineers at the California Institute of Technology (CalTech) and the University of California at Berkeley have developed a nanofocusing waveguide, a tiny passive plasmonic device which is capable of concentrating light onto a spot a few nanometers in size. In so doing, they have sidestepped the diffraction-limited nature of light, which normally prevents focusing light to a spot smaller than its own wavelength. This remarkable feat may lead to new optoelectronic applications in computing, communications, and imaging. Read More
If you were a scientist looking at a cell with a microscope, what would you do if you wanted get a look at the far side of that cell? You could try reaching in with a very fine-tipped pair of tweezers, but ... you’d probably be better off using something known as a fiber-optic spanner. Read More
When we first came across Emily Brooke's BLAZE, a bicycle attachment that projects a cycle lane symbol on the road ahead of the cyclist, it was little more than a concept. That was in June of last year. Since then, Brooke's launched her own company, developed working prototypes, and taken to Kickstarter to fund fabrication of the first batch. Read More
