This year’s Nobel Prize in Physics has been awarded to three physicists — Pierre Agostini at Ohio State University in Columbus, 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 developed methods that produce these ultrafast laser pulses, which can be used to study our world at the smallest scales and have applications in chemistry, biology and physics.
The prize was announced this morning by the Royal Swedish Academy of Sciences in Stockholm. The winners share a prize of 11 million Swedish kroner (US$1 million).
The laureates include the fifth woman ever to have been awarded the physics prize (see ‘Nobel imbalance’). Of 221 previous winners, just four have been women: Marie Curie in 1903 for her work on radiation phenomena, Maria Goeppert-Mayer in 1963 for unpicking some of the details of atomic structure, Donna Strickland in 2018 for work in laser physics and Andrea Ghez in 2020 for research into supermassive black holes.
L’Huillier was teaching when she received the call telling her that she had won. “The last half hour of my lecture was very difficult to do,” she said at a press conference after the prize announcement. “As you know, there are not many women that get this prize, so it’s very, very special.”
An object that moves too fast to be photographed produces the image of a band of light when its picture is taken. But using an extremely fast strobe light to illuminate the object can make it look like it has been frozen in time. Attosecond light pulses work by the same principle, opening up a world of phenomena once thought to be impossible to see.
Physicists who unravelled mysteries of black holes win Nobel prize
Pierre Agostini, a physicist at Ohio State University in Columbus, USA, and three others won the Nobel Prize in Physics 2023 for their research into attosecond pulses of light. Attosecond pulses are ultra-short laser pulses that can be used to study electrons at the smallest scales and have applications in chemistry, biology and physics.

Pierre Agostini (born July 23, 1941, Tunis, Tunisia) French physicist who was awarded the 2023 Nobel Prize in Physics for his experiments with attosecond pulses of light. He shared the prize with French physicist Anne L’Huillier and Hungarian physicist Ferenc Krausz. An attosecond is 10 −18 second, or a billionth of a billionth of a second.
