G 24 Hours Digital Bureau: ‘Attosecond’! This year’s Nobel Prize in Physics came out with a new word, which is not usually heard. The subject is related to electron dynamics. The key word is ‘attosecond pulse’. A method has been discovered to produce ‘attosecond pulses’ of light for a new experiment in the world of electrons! As a result, what happened to Nobel physics? In plain words, three scientists have now discovered a new way to explore the world of atoms and electrons!

But the discovery of that method came through experiments with light. On Tuesday, the 2023 Nobel Prize in Physics was awarded to two French scientists, Pierre Agostini, Anne L’Huillier, and Hungarian-Austrian scientist Ferenc Krause, for new research on light. According to the Royal Swedish Academy of Sciences, these three experiments with light have given mankind new tools to explore the world of electrons inside molecules.
Anne L’Huillier conducted an experiment. sent an infrared laser through the gas. He saw that a light wave is generated by the interaction of laser light with gas atoms. Much later Pierre Agostini produced light pulses lasting only 250 attoseconds. Around the same time, the experiments of Ferenc Krause produced light pulses with a duration of 650 attoseconds. And as a result of this, it is now possible to ‘study’ the scientific processes that happen very quickly which could not be measured until now.
He didn’t, but, the point is, what is this ‘attosecond’ object?

It’s a head-turner. 1 attosecond means– 1 quintillionth of 1 second; Its value is 0.0000000000000001. This attosecond pulse of light is important. He can measure electron acceleration processes where electrons change their energy.
