#Engineers create world's first white laser beam Researchers at Arizona State university have created the world's first white laser beam,
but white lasers could serve as a potential alternative light source both in people's homes and in the screens of their electronics.
Lasers are more energy efficient than LEDS, and the ASU researchers claim that their white lasers can cover 70 percent more colors than current standard displays.
The researchers also suggest the technology could be used beyond consumer electronics. They suggest white lasers could be used in Li-Fi
a developing technology that uses multiple colors of light to enable high-speed wireless internet access. Currently, LEDS are being used to develop Li-Fi technology,
and his colleagues argue that Li-Fi using white lasers could be 10 to 100 times faster than LED-based Li-Fi.
White lasers could serve as a potential alternative light sourcefor the past 50 years, lasers have been able to emit every single wavelength of light except for white.
The problem is that typical lasers only beam one specific wavelength of light at a time. To create white
the ASU researchers manufactured three thin semiconductor lasers each as thick as one-thousandth of a human hair
and lined them up parallel to one another. Each semiconductor emits one of the three primary colors
White lasers won't be showing up in our electronics any time soon, however. For this study, the researchers had to pump electrons into the semiconductors with an additional laser light.
The engineers will have to design white lasers to run on battery power before they can be used for commercial applications.
This image shows mixed emission color from the semiconductor lasers in the colors of red green, blue, yellow, cyan, magenta, and white.

#Researchers Develop Super-Hydrophobic Metal Surfaces Using Lasers Researchers have turned metal surfaces water repellent using femtosecond laser pulses.
Researchers from the University of Rochester have used femtosecond laser pulses to turn metals waterproof or super-hydrophobic.
said, his is the first time that a multifunctional metal surface is created by lasers that is super-hydrophobic (water repelling),
the laser treated metal surfaces can also absorb heat and light. The potential applications for anti-icing surfaces involve protection of aerofoils, protection of aerofoils, pipes of air conditioners and refrigerators, radar or telecommunication antennas,
titanium and brass to short bursts of lasers. These short burst lasted for only millionth of a billionth of a second.
These super powerful laser pulses produced microgrooves on top of which densely populated, lumpy nanostructures were formed. The optical and wetting properties of the surfaces of the three metals were altered by these nanostructures.
The nanostructures created by the lasers are intrinsic to the metal surface. According to the researchers, properties they provide to the metal will not deteriorate.
The super-hydrophobic properties of the laser-patterned metals are similar to the famous nonstick coating.
#Princeton Researchers Develop Rice Sized Laser Princeton university researchers have built a rice sized laser powered by single electrons tunneling through artificial atoms known as quantum dots.
#Researchers Develop Rice-Sized Laser That Can Boost Quantum computing Researchers have developed a microwave laser or maser,
Princeton university researchers developed a laser the size of a grain of rice, while investigating the use of semiconductor material fragments as components for quantum computing.
and not lasers. Quantum dots act like single atoms, as components for quantum computers. The maser is a tiny,
rice grain sized laser that is powered by a single electron from the artificial atoms called quantum dots.
