But how long is an attosecond, and what can these infinitesimally short pulses tell researchers about the nature of matter? I first learned of this area of research as a gradua
STOCKHOLM (Reuters) -Scientists Pierre Agostini, Ferenc Krausz and Anne L'Huillier won the 2023 Nobel Prize in Physics for creating incredibly short pulses of light that can capture processes inside atoms and molecules, in work which could advance medical diagnostics and electronics. 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 ability to generate attosecond pulses of light has opened the door on a tiny, extremely tiny, time scale and it's also opened the door to the world of electrons," said Eva Olsson, member of the Nobel Prize in Physics Selection Committee.
