- DiMauro said that Agostini’s work allowed scientists to capture the movement of electrons – which can move at the astonishing rate of 43 miles per second. Agostini and the other laureates created techniques to capture electrons using pulses of light that last just an attosecond – one quintillionth of a second.

At Politecnico di Milano, Mauro Nisoli leads the Attosecond Research Center. His group has contributed to the research that led to the generation and characterization of extremely short light pulses, with a duration of a billionth of a billionth of a second, that can be used to study electrons inside atoms and molecules as they move or change energy. This research won Pierre Agostini, Ferenc Krausz, and Anne L’Huillier this year's Nobel Prize in physics. Nature Italy talked with Nisoli about his group’s contribution to the award and their current projects.
What was your reaction to the award: was it a surprise to you?
I watched live the announcement from the Royal Swedish Academy and it filled me with joy. I had no doubt that sooner or later the field of attoseconds would be awarded a Nobel Prize. There had been some recent signals. In 2022 the Wolf Prize for physics was awarded to L'Huillier, Krausz, and Paul Corkum. In August this year, I was at a Nobel Symposium organized in Båstad on attosecond science, and observers from the Nobel Academy were there too. I am very proud that my group gave its contribution to this field of research from the very beginning.
How did you contribute?
To obtain attosecond pulses, a high energy pulsed laser beam is directed toward a noble gas. The duration of the laser pulses influences the attosecond signal emitted from the gas. In the mid 90s, Ferenc Krausz was experimenting in Vienna with laser pulses of nearly 25 femtoseconds (a thousand times longer than attoseconds) which he was interested in compressing further. In the same period, with Orazio Svelto and Sandro De Silvestri [also from Politecnico di Milano], we developed a new technique for the compression of high energy laser pulses. It is based on the use of a hollow fibre with a diameter of a few hundreds of microns, filled with noble gas. When the laser travels along such fibre, it acquires new frequencies. We then used special mirrors to make these frequencies interfere with each other to finally produce a shortened laser pulse. We first demonstrated the technique in 1996 with the compression of 140 femtoseconds down to 10 femtoseconds and presented it in international conferences. Soon after, Ferenc Krausz contacted us, and I spent some time in his laboratory. There, in 1997, we obtained 4.5 femtoseconds laser pulses, at the time the shortest ever produced, which Krausz then used to irradiate a noble gas and produce isolated attosecond pulses, instead of a train of pulses.
