Single light wave flashes out from fibre laser

Super-short light pulses marks a milestone in optical technology (Image: Kim Steele/Getty)

A long-elusive goal of physics has been reached – producing a pulse of light so short that it contains just a single oscillation of a light wave.
The flashes are almost as short as a light pulse can be, according to the laws of physics. The new super-short pulses could used as flashguns to sense very small, very fast events such as a single photon interacting with a single electron, says Alfred Leitenstorfer of the University of Konstanz in Germany. A single-cycle pulse packs in energy more densely than a pulse containing more wave peaks and troughs.
They could also show the way to boosting data transmission through fibre-optic cables, by shrinking the minimum amount of light needed to encode a single digital 1 or 0.
Leitenstorfer's group shunned the crystalline lasers typically used by physicists looking to make super-short light pulses and used optical-fibre lasers and wavelengths of light like those standard in telecommunications.....
