Engineers improve NASA lidar tech for exploration

Lidar technology improvements will help NASA scientists and explorers with remote sensing and surveying, mapping, 3D-image scanning, hazard detection and avoidance, and navigation.

New nanoparticle source generates high-frequency light

High-frequency light is useful. The higher the frequency of light, the shorter its wavelength—and the shorter the wavelength, the smaller the objects and details the light can be used to see.

Researchers develop ultraefficient white light laser on a chip

A team of researchers from the University of Twente has made a breakthrough in ultraefficient on-chip supercontinuum generation. The findings, published in the journal Advanced Photonics Research, represent a major step forward ...
