Ultrafast lasers create 3D crystal waveguides in glass

Ultrafast lasers create 3D crystal waveguides in glass

June 12, 2015: Researchers from Lehigh University, Japan and Canada have advanced a step closer to the dream of all-optical data transmission by building and demonstrating what they call the ?world?s first fully functioning single crystal waveguide in glass.? In an article published in Scientific Reports, a Nature publication, the group said it had employed ultrafast femtosecond lasers to produce ...

Laser beam compressed into thin filament

Laser beam compressed into thin filament

June 2, 2015: A group of Russian scientists recently presented their research into the process of laser pulse filamentation?the effect produced when a laser beam propagating in air focuses into a filament. The researchers discovered how this process influences the preliminary transition of a beam passing through quartz glass, which has applications in the field of nonlinear optics. What is ...

Tremendous need for high-power, reliable lasers in telecom predicted

Tremendous need for high-power, reliable lasers in telecom predicted

May 18, 2015: Since lasers were invented in 1960, they have penetrated countless scientific, industrial and recreational fields?from eye surgery to DVD players, from cutting steel to triggering ignition in missile stages. That last use is a target market for Alfalight, a University of Wisconsin-Madison spinoff that set out in 1999 to use patented technology to make lasers for the ...

Researchers use LED and laser lights to test gold on-site

Researchers use LED and laser lights to test gold on-site

April 30, 2015: University of Adelaide researchers are developing a portable, highly sensitive method for gold detection that would allow mineral exploration companies to test for gold on-site at the drilling rig. Instead of utilising x-ray technology, the prototype uses LED and laser lights to detect gold mineralisation in the soil removed from a drill hole. Using light in two ...

Scientists trying to shoot down space debris with laser

Scientists trying to shoot down space debris with laser

By BizLED Bureau April 20, 2015: A group of scientists at Japan?s Riken Research Institute are developing a system to remove debris from the space orbit with the help of laser. Satellites continuously revolve round the planets and spacecrafts, which create debris. The debris creates a hazard to satellites and spacecrafts. Scientists are trying to remove the debris with the ...
