Igniting the air for atmospheric research
Vienna, Austria (SPX) Feb 20, 2015
It looks a bit like a lightsaber from Star Wars: when an extremely intense laser pulse is sent through the air, it can focus itself, creating a narrow filament of light. By shooting such filaments into the sky and analysing back-scattered light, it would be possible to trace pollutants in the atmosphere.
To achieve this, lasers with mid-infrared wavelengths are required. However, reaching —> Read More Here
