Researchers say they are finally unraveling the effects of ultrafast lasers that can change material states in attoseconds —one-billionth of one-billionth of a second—the time required to complete one light wave’s optical cycle.

The new Israeli research opens up new avenues for scientists to observe light closely in laboratory settings. Under these conditions, a wave crosses a hydrogen atom in a single attosecond, compared to the time required for light to move from Earth to the Moon.

Beyond its immediate use, the development may drive future speed advancements in communications and computing by increasing researchers’ understanding of high-speed quantum light and matter interactions.
