Skarp Razor shaves with lasers instead of metal blades

Laser technology has come a long way over the decades, having made leaps from science fiction to science fact within the medical field, manufacturing, and even as a "death star" beam to help unlock the mysteries of the universe. But the latest laser-enabled concept is something the average consumer can more readily appreciate. The Skarp Razor may become the first-ever personal shaving tool powered by a laser.Read More

World's first white laser demonstrated

Incandescent bulbs, LEDs, and CFLs may soon have to budge up because a new lighting technology is in town – white lasers. Using nanotechnology to create a bespoke semiconducting material, a team of scientists at Arizona State University has developed a laser that can produce white light that is brighter and more efficient than LEDs.Read More

Sure Hang aims to make the laser level more useful

When it comes to hanging things on a wall in a straight line, a laser level can go a long way towards making that easier to accomplish. A new device called Sure Hang aims to make the laser level even more useful by allowing it to integrate directly with a tape measure for hanging things up at a perfect interval along a level, straight line.Read More

Laser device may soon non-invasively monitor diabetics' glucose levels

In order to monitor their blood glucose levels, diabetics typically have to perform painful and inconvenient finger-prick blood tests – in some cases, several times a day. Using an implantable glucose-monitoring sensor is one alternative, although it must be surgically installed and subsequently removed for replacement. Another option may be on the way, however, in the form of a device that simply shines a laser on the user's finger.Read More

MIT physicists build world's first fermion microscope

MIT researchers claim to have created a method to better observe fermions – the sub-atomic building blocks of matter – by constructing a microscope capable of viewing them in groups of a thousand at a time. A laser technique is used to herd the fermions into a viewing area and then freeze them in place so all of the captured particles can be imaged simultaneously.Read More

The amazing technicolor liquid nanolaser

A new nanoscale plasmon laser developed at Northwestern University changes color in real time through a process as simple as swapping one liquid dye for another. The scientists responsible for the technology claim this is the world's first liquid nanoscale laser, and it could find uses in medical diagnostics as well as military or security applications.

Lasers could be used to zap orbital debris

Orbital debris is increasingly becoming a hazard to satellites and other spacecraft, which is why various groups have proposed concepts such as gas clouds, nets and sails for collecting it. While those approaches could capture larger objects, the problem of smaller pieces of debris – which whiz around the Earth like bullets – would remain. That's why an international group of scientists is developing a system that could shoot those bits down with a laser. Read More

World’s most powerful laser diode arrays deployed

The High-Repetition-Rate Advanced Petawatt Laser System (HAPLS) under construction in the Czech Republic is designed to generate a peak power of more than 1 quadrillion watts (1 petawatt, 1015 watts). The key component to this instrument – the laser "pump" – will be a set of solid-state laser diode arrays recently constructed by Lawrence Livermore National Laboratory (LLNL). At peak power, this electronic assemblage develops a staggering 3.2 million watts of power and are the most powerful laser diode arrays ever built.Read More
