3 scientists shared the prize 'for experimental methods that generate attosecond pulses of light for the study of electron dynamics in matter.'

The U.S. National Science Foundation congratulates Pierre Agostini, Ferenc Krausz and Anne L'Huillier on their 2023 Nobel Prize in physics. Their groundbreaking discoveries have given humanity new tools for exploring the world of electrons inside atoms and molecules and paved the way for the creation of new technologies.

NSF is proud to have supported the work of Agostini. Over the course of his career, he has received four awards for his experiments in strong field physics and on the atom's response to ultra-fast bursts of electromagnetic radiation. For decades, NSF has funded research on lasers — like the beam of light used by the laureates' during their experiments — attoseconds and the basic laws governing the physical world.

The U.S. National Science Foundation propels the nation forward by advancing fundamental research in all fields of science and engineering. NSF supports research and people by providing facilities, instruments and funding to support their ingenuity and sustain the U.S. as a global leader in research and innovation. With a fiscal year 2023 budget of $9.5 billion, NSF funds reach all 50 states through grants to nearly 2,000 colleges, universities and institutions. Each year, NSF receives more than 40,000 competitive proposals and makes about 11,000 new awards. Those awards include support for cooperative research with industry, Arctic and Antarctic research and operations, and U.S. participation in international scientific efforts.
