Physicists who built ultrafast ‘attosecond’ lasers win Nobel Prize

This year’s Nobel Prize in Physics has been awarded to three physicists — Pierre Agostini at Ohio State University, US, Ferenc Krausz at the Max Planck Institute of Quantum Optics in Garching, Germany, and Anne L’Huillier at Lund University, Sweden — for their research into attosecond pulses of light.

Attosecond physics allows scientists to look at the very smallest particles at the very shortest timescales (an attosecond is one-quintillionth of a second, or one-billionth of a nanosecond). The winners all developed experiments to be able to produce these ultrafast laser pulses, which can be used to probe our world at the smallest scales and have applications across chemistry, biology and physics.
