Fastest-ever flashgun captures image of light wave - tech - 19 June 2008 - New Scientist Tech

"In the future, Goulielmakis hopes to produce light pulses of 24 attoseconds, the atomic unit of time, defined as how long it takes an electron to travel from one side of a hydrogen atom to the other.

But Marangos thinks even shorter pulses are possible. 'There's nothing magical about the atomic unit of time,' he says, saying zeptosecond pulses of trillionths of a billionth of a second might be possible. These would be capable of imaging the movement of nuclear particles like protons, says Marangos."
