Sweden's most powerful laser delivers record-short light pulses

For the first time, researchers at Umeå University have demonstrated the full capabilities of their large-scale laser facility. In a study published in Nature Photonics, the team reports generating a combination of ultrashort laser pulses, extreme peak power, and precisely controlled waveforms that make it possible to explore the fastest processes in nature.

What happens in the time period it takes light to cross the diameter of your hair? This is the femtosecond, a millionth of a billionth of a second.

In order to take movies with femtosecond time resolution, we need ultrafast #cameras – flashes of light that act faster than any #camera #shutter ever could.

Whaaaa? Are we getting close to breaking the speed of light?
