The Royal Swedish Academy of Sciences awards the Nobel Prize in Physics 2023.
A professor at The Ohio State University, Columbus, USA, is one of the laureates.
Director at Max Planck Institute of Quantum Optics, Garching and professor at Ludwig-Maximilians-Universität München, Germany
A professor at Lund University, Sweden, is the third laureate.
The laureates are awarded for their experimental methods that generate attosecond pulses of light for the study of electron dynamics in matter.
The prize amount is 11 million Swedish kronor, shared equally between the laureates.
They have demonstrated a way to create extremely short pulses of light that can measure rapid processes in which electrons move or change energy.
In 1987, Anne L’Huillier discovered that many different overtones of light arose when she transmitted infrared laser light through a noble gas.
In 2001, Pierre Agostini succeeded in producing and investigating a series of consecutive light pulses, each lasting just 250 attoseconds.
At the same time, Ferenc Krausz was working with another type of experiment that made it possible to isolate a single light pulse that lasted 650 attoseconds.
