Tubular laser beams can create what amount to fiber-optic cables made of thin air, researchers report in a study to appear in Physical Review X. Laser-heated air can efficiently transmit light signals ...

Sometimes called the "Oscars of Invention," R&D Magazine's R&D 100 Awards have for nearly 50 years honored game-changing technologies, from the flashcube (1965) to high-definition television (1998).

A large group of fiber optic lasers are powered by DC current. Laser drive is supplied by a current source with modulation added further along the signal path. The current source, although ...

The company formerly known as LaserMotive is coming out of stealth mode with a new name — PowerLight Technologies — and a sharper focus on beaming power over fiber-optic cables. “The company has gone ...

Emerging fiber laser technologies are expected to make significant market progress in sensing and healthcare, while innovations in laser welding and 3D printing mean that material processing remains ...

A new light control system created at CU Boulder could increase the capacity for fiber optic technologies, enable thinner medical endoscopes and allow for stronger industrial lasers. Many current ...

A new technology in the fiber-optics market is striking the right note with investors and raising cash at a time when industry confidence is low and venture capital is hard to find. A number of ...

Diagnosing a muscular disorder, disease or infection often requires a sample of the tissue to be extracted, but these biopsies can be painful and difficult to perform. Researchers at the ...

Researchers at The Johns Hopkins University have been awarded a grant from NASA to develop a fiber-optic laser system for the monitoring of the earth's air pollution and atmospheric changes. Jin Kang, ...

Brainiac75] is a fan of fiber optic lamps, except for one thing—they’re often remarkably dim. Thus, they set out to hack the technology to deliver terrifying amounts of light while still ...
