Anne L'Huillier

Anne L'Huillier is a French-Swedish physicist renowned for her groundbreaking experimental work in attosecond physics, the study of ultrafast processes in atoms and molecules. Her pioneering research on high-harmonic generation laid the experimental foundation for generating and measuring attosecond light pulses, enabling scientists to observe electron dynamics in real time. A professor of atomic physics at Lund University in Sweden, she was awarded the Nobel Prize in Physics in 2023, sharing it with Pierre Agostini and Ferenc Krausz.

Early life and education

Born in Paris, L'Huillier developed an early interest in mathematics and the natural sciences. She pursued her higher education at the École Normale Supérieure de Fontenay-aux-Roses and later at the Pierre and Marie Curie University (now Sorbonne University). Under the supervision of Bernard Cagnac, she completed her doctoral thesis in 1986 on multiphoton ionization in xenon, a topic that positioned her at the forefront of laser physics and nonlinear optics. Her postdoctoral research took her to the University of Southern California and the Lawrence Livermore National Laboratory, where she worked with leading figures in the field of ultrafast laser science.

Career and research

L'Huillier began her independent research career in France at the Commissariat à l'énergie atomique et aux énergies alternatives (CEA) in Saclay. In 1995, she moved to Sweden to join the faculty at Lund University, a major European center for laser research home to the Lund Laser Centre. At Lund, she established a leading experimental group focused on strong-field physics and high-order harmonic generation. Her work there was instrumental in transforming high-harmonic generation from a scientific curiosity into a robust tool for creating coherent extreme ultraviolet and X-ray light, with critical applications in probing matter at the most fundamental timescales.

Attosecond physics contributions

L'Huillier's most significant contributions revolve around the experimental mastery of high-harmonic generation. In seminal experiments, her team at Lund University demonstrated how an intense infrared laser pulse focused into a noble gas like argon could produce a train of attosecond pulses in the extreme ultraviolet spectrum. This work provided the key methodology for the attosecond measurement techniques later refined by Pierre Agostini and Ferenc Krausz. Her research has enabled direct observation of previously inaccessible phenomena, such as electron motion during chemical bond formation and the dynamics of photoionization in atoms like helium. These advances have defined the field of attosecond science.

Awards and honors

L'Huillier has received numerous prestigious awards recognizing her transformative impact on physics. She was awarded the Wolf Prize in Physics in 2022 and the BBVA Foundation Frontiers of Knowledge Award in the same year. In 2023, she became the fifth woman to receive the Nobel Prize in Physics, a honor she shared with her colleagues for their experimental methods generating attosecond light pulses. She is a member of the Royal Swedish Academy of Sciences, the Académie des Sciences in France, and the American Physical Society. She has also been honored with the Carl Zeiss Research Award and the L'Oréal-UNESCO For Women in Science Awards.

Personal life

L'Huillier is married to Claude L'Huillier, also a physicist, and they have two children. She became a naturalized citizen of Sweden in the 1990s. An advocate for women in science, she has spoken about the challenges and rewards of balancing a demanding research career with family life. Outside of her laboratory at Lund University, she enjoys activities such as hiking and is an avid reader of history and literature.
