STOCKHOLM: France’s Pierre Agostini, Hungarian-Austrian Ferenc Krausz and French-Swedish Anne L’Huillier were awarded the Nobel Physics Prize on Tuesday for research into tools for exploring electrons inside atoms and molecules.
The trio was honoured “for experimental methods that generate attosecond pulses of light for the study of electron dynamics in matter”, the jury said, adding that the research had potential applications in both electronics and medical diagnostics. “An attosecond is so short that there are as many in one second as there have been seconds since the birth of the universe” over 13 billion years ago, it added.
In 1987, L’Huillier “discovered that many different overtones of light arose when she transmitted infrared laser light through a noble gas,” the Nobel Committee noted, adding that she has continued to explore this phenomenon, “laying the ground for subsequent breakthroughs”.In the early 2000s, Agostini and Krausz worked on experiments that made it possible to isolate light pulses that lasted only a few hundred attoseconds.
Before L’Huillier, Marie Curie , Maria Goeppert Mayer , Donna Strickland and Andrea Ghez are the only women to have won the award. “In my work, I see two things, one of which is very fundamental. Which is to really understand, I mean, look at electrons and look at their properties,” L’Huillier said.
