Fujifilm will introduce 1TB optical disc in 2015

(Phys.org)—Fujifilm is working on a new recording method for optical discs. It has developed the new method through the use of two-photon absorption in order to generate heat, and the report in TechOn! notes that this two-photon ...

The Power of Light: Moving Macroscopic Amounts of Matter

(PhysOrg.com) -- Since 1970, scientists have been working with “optical tweezers” - lasers that move microscopic amounts of matter using forces originating from the light matter interaction. Now, for the first time, researchers ...

Quantum optical cooling of nanoparticles

When a particle is completely isolated from its environment, the laws of quantum physics start to play a crucial role. One important requirement to see quantum effects is to remove all thermal energy from the particle motion, ...

'Optical rocket' created with intense laser light

In a recent experiment at the University of Nebraska–Lincoln, plasma electrons in the paths of intense laser light pulses were almost instantly accelerated close to the speed of light.

New laser technology could divert lightning strikes

(Phys.org) —Optical scientists at the University of Arizona and the University of Central Florida have developed a technology capable of sending high-intensity laser beams through the atmosphere much farther than was possible ...

Scientists make quantum breakthrough

(PhysOrg.com) -- Scientists have demonstrated for the first time that atoms can be guided in a laser beam and possess the same properties as light guided in an optical communications fiber.

Cheap and quick HIV testing made possible with DVD scanners

Thanks to USB sticks and video streaming, DVD players are becoming all but obsolete. But their cheap optics may find a new life in a cost-effective and speedy technique for on-the-spot HIV testing and other analytics.

Print your own lasers, lights and TV screens

Imagine printing your own room lighting, lasers, or solar cells from inks you buy at the local newsagent. Jacek Jasieniak and his colleagues at CSIRO, the University of Melbourne and the University of Padua in Italy, have ...
