X-ray lasers: Why does brighter mean darker?
When we illuminate something, we usually expect that the brighter the source we use, the brighter the resulting image will be. This rule also works for ultra-short pulses of laser light—but only up to a certain intensity. The answer to the question.....»»
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.....»»
Supply chain backs rumors Apple will make several OLED iPads
Most previous rumors have centered on Apple making a 12.9-inch iPad Pro with an OLED display, but new evidence suggests that will just be the first of many.Eventually, Apple is going to put OLED displays in all iPads, because it provides brighter scr.....»»
Forget Lasers. The Hot New Tool for Physicists Is Sound

Pixel 7 Pro could come with a much brighter display
According to Android 13’s source code, it has been suggested that the upcoming Pixel 7 Pro could feature a considerably brighter display. The post Pixel 7 Pro could come with a much brighter display first appeared on Phandroid. Not all sm.....»»
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.....»»
Photonic integrated erbium doped amplifiers reach commercial performance
Erbium-doped fiber amplifiers (EDFAs) are devices that can provide gain to the optical signal power in optical fibers. They are often used in long-distance communication fiber optic cables and fiber-based lasers. Invented in the 1980s, EDFAs have pro.....»»
Ultrafast lasers used to probe next-generation solar cells
Researchers have tracked the first fractions of a second after light strikes solar cells, providing insights into how they produce electricity......»»
How to enable dark mode for Microsoft Edge
One of the features of Microsoft Edge is the ability to enable dark mode. This gives the overall UI a darker tone that will make it less glaring in low-light. The post How to enable dark mode for Microsoft Edge first appeared on Phandroid......»»
Uncovering a novel way to bring the energy that powers the sun and stars to Earth
Scientists at the U.S. Department of Energy's (DOE) Princeton Plasma Physics Laboratory (PPPL) have uncovered critical new details about fusion facilities that use lasers to compress the fuel that produces fusion energy. The new data could help lead.....»»
Modifying surfaces with polymer chains promotes uniform drying of particle-containing liquids
What do coffee, red wine and ink have in common? The stubborn stains they leave behind. Anyone who has ever knocked over a cup of coffee will know that coffee dries in an unusual pattern, the stain is lighter at the center but it gets darker around t.....»»
Using mirrors, lasers and lenses to bend light into a vortex ring
A team of researchers from the University of Shanghai for Science and Technology and the University of Dayton has developed a way to bend light into a vortex ring using mirrors, lasers and lenses. In their study, published in the journal Nature Photo.....»»
A brighter business outlook in the States is one reason Canadian dealer groups are buying U.S. stores
It's not just warmer U.S. weather, but also the promise of a brighter outlook for business that is drawing interest from Canadian dealer groups......»»
How Ants Inspired a New Way to Measure Snow With Space Lasers
Photons wander through snow like ants through a nest. That inspired a clever new NASA technique for measuring the fluffy stuff from orbit......»»
Instagram announces visual refresh with brighter icon, new typography, no iPad app
Instagram, the photo-sharing social network that lacks the resources required to develop an iPad app, is now introducing a visual refresh to its app. Apart from a brighter icon, the company has also developed its own typography, while highlighting.....»»
Diamond mirrors for high-powered lasers
Just about every car, train and plane that's been built since 1970 has been manufactured using high-power lasers that shoot a continuous beam of light. These lasers are strong enough to cut steel, precise enough to perform surgery, and powerful enoug.....»»
Two Military Satellites Just Communicated With Each Other Using Space Lasers
Two satellites recently exchanged more than 200 gigabits of data over a distance of about 60 miles (100 kilometers) using laser communication in space. Gizmodo reports: Satellites generally don't communicate directly with each other. Instead, they us.....»»
Generating ultra-violet lasers with near-infrared light through "domino upconversion" of nanoparticles
Strong and coherent ultraviolet light emission devices have enormous medical and industrial application potential, but generating ultraviolet light emission in an effective way has been challenging. Recently, a collaborative research team co-led by r.....»»
