These optical scanners comprise two separate, perpendicular planar mirrors that rotate independently. They are positioned in a manner wherein laser light bouncing off the first mirror (axis 1) ...

Australian-US team says wavefront-shaping of input light lifts power threshold for SBS scattering by an order of magnitude. A narrowband laser beam shaped by a spatial light modulator excites many ...

WASHINGTON — Researchers have developed a new all-optical method for driving multiple highly dense nanolaser arrays. The approach could enable chip-based optical communication links that process and ...

A doughnut-shaped laser was used to create a 45-metre-long optical fibre out of air, and a pulse of light was then sent through it. The technology could eventually be used to detect radioactive ...
