in cooperation with Thales Research and Technology in the United kingdom, say the tuneable laser source integrated on silicon is a groundbreaking achievement in efforts to secure fully integrated transceivers.

and the Proceedings of the National Academy of Sciences the technology involves beaming a high-powered laser onto a powder for an extremely short amount of time#about a trillionth of a second.

#Laser device sniffs out tiny traces of explosives University of California Berkeley rightoriginal Studyposted by Sarah Yang-Berkeley on July 24 2014mechanical engineers have found a way to dramatically increase the sensitivity of a light-based plasmon sensor.

which work by detecting shifts in the wavelength of light Zhang says. he difference in intensity is similar to going from a light bulb for a table lamp to a laser pointer.

the new method for enriching stable isotopes, called MAGIS (magnetically activated and guided isotope separation), needs little energy due to its use of low-powered lasers and permanent magnets.

and control the routing of light in devices too tiny for conventional lasers. The researchers have shown how to control the intensity

and hit them with high-powered lasers you see them for a fraction of a second to upwards of a few seconds

When pumped by a strong laser these quantum degenerate particles gathered energy and released it as light at the Fermi edge:

or the batteries have no charge remaining. n addition to the applications discussed above such technology could be extended to other radiations such as magnetic resonance imaging (MRI) and light detection and ranging (LIDAR)

materials science. ecause it employs commercial lasers and low-cost mass-production techniques the researchers believe it will set the stage for new generations of abletopaccelerators.

#Electrically driven polariton lasers Kim says would operate using one-hundredth of the power of conventional lasers

and conventional lasers waste energy unnecessarily exciting electrons to higher energy levels even when the lower levels are too full to accept the excited electrons

The current iteration of the polariton laser requires two to five times less energy than a comparable conventional laser

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."

Choreographed high-power lasers or electron beams can fuse and sculpt metal powders into high-performance machine parts.

In 2008 scientists at the Lawrence Livermore National Laboratory in California produced large quantities of antimatter by directing an extremely powerful laser at a tiny gold disc.

and weld even through a half-inch of steel at greater efficiencies than today s industrial lasers.

Huang says Terablade represents a third generation of industrial lasers. The first generation which evolved a few decades ago was carbon dioxide lasers in

This means the Terablade operates with just as much power and brightness as all other industrial lasers about 2600 megawatts per square centimeter per steradian at roughly 40 percent efficiency.

An individual diode laser in say a laser pointer can emit a beam in infrared and near-infrared wavelengths that can be focused tightly to a very small spot

Other customers include top global builders of industrial laser-based machines and system integrators. More broadly our vision is to revolutionize the laser industry Huang says by introducing powerful direct-diode lasers to various applications across the globe.

anyone could image the particles after shining near-infrared light on them with a laser pointer. The researchers are also working on a smartphone app that would further process the images

#3-D images with only one photon per pixel Lidar rangefinders which are common tools in surveying

In this week s issue of the journal Science researchers from MIT s Research Laboratory of Electronics (RLE) describe a new lidar-like system that can gauge depth

Since a conventional lidar system would require about 100 times as many photons to make depth estimates of similar accuracy under comparable conditions the new system could yield substantial savings in energy and time

and it works much more reliably than lidar in bright sunlight when ambient light can yield misleading readings.

All the hardware it requires can already be found in commercial lidar systems; the new system just deploys that hardware in a manner more in tune with the physics of low light-level imaging and natural scenes.

In a conventional lidar system the laser fires pulses of light toward a sequence of discrete positions

which contrasted the new system s performance with that of a conventional lidar system. They ve used a very clever set of information-theoretic techniques to extract a lot of information out of just a few photons

while a Lidar system captures 3-D images to discern building facades from the physical environment.

That when they had to install the Lidar system, to better differentiate building facades from the surrounding environment.

"but you need a powerful laser, and, even so, the material needs to be a many micrometers

By using powerful lasers however, second harmonic generation (SHG) chiroptical effects emerge, which are typically three orders of magnitude stronger.

The Zebedee is a laser scanner not an infrared scanner like the Kinect or most of the other 3-D scanners we come across.

The laser scanner sits on a spring bouncing comically and uncontrollably back and forth pointing all over the place as it does.

Key to Cyark is a portable eye-safe laser scanner made by Cyark founder Ben Kacyra.

The scanner is a LIDAR system which is like radar except instead of bouncing back radio waves it uses lasers.

LIDAR systems existed before Cyark but they were used mainly in labs where someone would bring an object

This picosecond timer gives the laser scans accuracy down to a millimeter. With the technology already made it took a tremendous act of destruction to inspire its use in historical preservation.

"Interestingly, a conventional laser beam (a laser pointer)' s shape and polarization can also be nonseparable.""To make the laser beam's shape and polarization nonseparable,

It also appears to be fashionable to compare output power of cutting lasers to laser pointers,

with many noting that the new diamond laser is equal to 00,000 laser pointers. In light of the ample variance in both wavelength and power of pointer devices, those kinds of comparisons should probably be taken as rough.

When you shine a red laser pointer at a wall, for example, your eye detects red light. However, for all materials, there is a tiny amount of light bouncing off at integer multiples of the incoming frequency.

So with the red laser pointer, there will also be some blue light bouncing off of the wall.

this is accomplished by synchronizing the projector so that as the laser scans a particular plane, the camera accepts light only from that plane.
