Scientists Pierre Agostini, Ferenc Krausz and Anne L'Huillier won the 2023 Nobel Prize in Physics for "experimental methods that generate attosecond pulses of light for the study of electron dynamics in matter", the award-giving body said on Tuesday.

The prize, which was raised this year to 11 million Swedish crowns (about $1 million), is awarded by the Royal Swedish Academy of Sciences.

"The laureates' experiments have produced pulses of light so short that they are measured in attoseconds, thus demonstrating that these pulses can be used to provide images of processes inside atoms and molecules," the award-giving body said in a statement.

Physics is the second Nobel to be awarded this week after Hungarian scientist Katalin Kariko and U.S. colleague Drew Weissman won the medicine prize for making mRNA molecule discoveries that paved the way for Covid-19 vaccines.

Created in the will of dynamite inventor and businessman Alfred Nobel, the prizes for achievements in science, literature and peace have been awarded since 1901 with a few interruptions, becoming the arguably highest honour for scientists everywhere.

While the award for peace can hog the limelight, the physics prize has likewise often taken centre stage with winners such as Albert Einstein and awards for science that has fundamentally changed how we see the world.

Last year, Alain Aspect, John Clauser and Anton Zeilinger won the prize for work on quantum entanglement, where two particles are linked regardless of the space between them, something that unsettled Einstein himself who once referred to it as "spooky action at a distance".

Announced on consecutive weekdays in early October, the physics prize announcement will be followed by ones for chemistry, literature, peace and economics, the latter a later addition to the original line-up. ($1 = 11.0129 Swedish crowns)
