Using air to deflect lasers
Using a novel method, beams of laser light can be deflected using air alone. An invisible grating made only of air is not only immune to damage from the laser light, but it also preserves the original quality of the beam, reports an interdisciplinary.....»»
Taking solar-powered lasers to new heights with four-mirror pumping
The design of efficient solar cells, which harness energy to generate electricity or produce hydrogen by splitting water, has received much attention globally. Another route to harnessing abundant, free solar energy: using it as a pumping source for.....»»
New on-chip laser frequency comb is 100 times more efficient than previous versions
On-chip laser frequency combs—lasers that emit multiple frequencies or colors of light simultaneously separated like the tooth on a comb—are a promising technology for a range of applications including environmental monitoring, optical computing,.....»»
Application of non-Bravais lattices to light control technology
A novel light-manipulating technology has been developed by an international team, including Kyoto University, that can be applied to lasers, sensors, and nonlinear optics......»»
Cold brew coffee—pew, pew, pew—brewed with lasers!
A new laser technology creates cold brew coffee in minutes. Even better: it tastes just as good and may be coming to a coffee shop near you. “Nobody wants to wait for 12 or 24 hours to get a cup of coffee,” says Anna Rosa Ziefuss, the G.....»»
Researchers realize two coherently convertible qubit types using a single ion species
Trapped ion computers are quantum computers in which the qubits (quantum units of information) are ions trapped by electric fields and manipulated with lasers. To avoid crosstalk between nearby qubits, physicists and engineers design these computers.....»»
The future of NASA"s laser communications
NASA uses lasers to send information to and from Earth, employing invisible beams to traverse the skies, sending terabytes of data—pictures and videos—to increase our knowledge of the universe. This capability is known as laser, or optical, commu.....»»

Imagine trying to summon the sun to your research laboratory......»»
Researchers create nanoparticle-vaccine combination to target melanoma
Cancers in humans have all sorts of ways to survive and thrive: Cells and tumors alike engage in devious means to deflect, deceive, and evade detection by our bodies' immune systems......»»
How lasers and lidar are changing the way wearables track health
An incredible new sensor technology may make it possible for future wearables to accurately measure everything from our blood pressure to hydration levels......»»
Researchers use lasers to new view on Oregon"s glaciers
The latest technology to study glaciers fits in a backpack and can be carried up steep mountains......»»
"Life-like" lasers can self-organize, adapt their structure, and cooperate
By mimicking features of living systems, self-organizing lasers could lead to new materials for sensing, computing, light sources and displays......»»
When light and electrons spin together
Theoreticians at the MPSD have demonstrated how the coupling between intense lasers, the motion of electrons, and their spin influences the emission of light on the ultrafast timescale. Their work has been published in npj Computational Materials......»»
MIT Scientists Propose "Space Bubbles" to Deflect Solar Radiation, Ease Climate Change
Popular Science reports: A raft of thin-film silicon bubbles deployed from Earth into outer space and stretching to the size of Brazil could potentially block the Sun's solar radiation from further warming Earth, possibly helping to not only stave o.....»»
Using lasers and "tow-trucks", Japanese firms target space debris
From laser beams and wooden satellites to galactic tow-truck services, start-ups in Japan are trying to imagine ways to deal with a growing environmental problem: space debris......»»
Lasers light the way to discovery of ancient crust beneath Western Australia
By firing lasers finer than a human hair at tiny grains of a mineral extracted from beach sand, Curtin researchers have found evidence of an almost four billion-year-old piece of the Earth's crust that lies beneath the South-West of WA......»»
U.S. and Czech scientists collaborate to explore gamma-ray production with high-power lasers
The U.S. National Science Foundation and the Czech Science Foundation, or GACR, are partnering on a new collaborative project of scientists from the University of California San Diego and Extreme Light Infrastructure Beamlines in the Czech Republic w.....»»
Miniaturized, highly sensitive ultrasound sensor for photoacoustic imaging
Photoacoustic imaging generates ultrasound waves by irradiating biological tissues with pulses or modulated continuous lasers. Ultrasound sensors are used to capture ultrasound signals in a distributed manner. Then, the light absorption distribution.....»»
Forget Lasers. The Hot New Tool for Physicists Is Sound
From acoustic tweezers to holograms, engineers are taking inspiration from the field of optics—and riding the sound wave......»»
Researchers built a laser that can supposedly run forever
Researchers have managed to create a never-ending laser they say can run forever. Unlike normal light-powered lasers, this laser draws its power from a special phase of matter. The researchers published their findings on the laser in the journal Natu.....»»
Building a large 40W C02 Laser For Under $700
Lasers are awesome. We all know this. If you don’t have one, you want one. Owen wanted one, but had a fairly tight budget. When searching, he found the ones in his price range to be too small. So he built one! I know that there are some of you.....»»
