Fastest-ever flashgun captures image of light wave



“Researchers have found a way to generate the shortest-ever flash of light – 80 attoseconds (billionths of a billionth of a second) long. […] The light pulses are produced by firing longer, but still very short laser pulses into a cloud of neon gas. The laser gives a kick of energy to the neon atoms, which then release this energy in the form of brief pulses of extreme ultraviolet light.” (story)
