Pierre Agostini, winner of the 2023 Nobel Prize in Physics, managed to create and investigate a series of consecutive light pulses, with each pulse lasting only 250 attoseconds. At the same time, co-laureate Ferenc Krausch was working on another type of experiment that made it possible to emit a single pulse of light lasting 650 attoseconds.

Ann Lhuillier discovered that when infrared laser radiation passes through an inert gas, many different shades of light appear.

Each overtone is a light wave with a certain number of cycles for each cycle in the laser light. They arise as a result of the interaction of laser light with atoms in the gas; This gives some electrons extra energy, which is then emitted as light. Lhuillier continued to explore this phenomenon and laid the foundation for subsequent breakthroughs.

What is the Nobel Prize?

The Nobel Prize was founded in Sweden in the 19th century by the famous businessman and chemist Alfred Nobel. This award remains an important recognition for individuals who have made outstanding contributions to the advancement of humanity.

• The first awards since the Nobel Prize’s founding were awarded in 1901, after Nobel’s death five years earlier.
• To ensure the selection of esteemed laureates, Nobel selected a few distinguished institutions for each category. The Royal Swedish Academy of Sciences was tasked with awarding prizes in chemistry and physics, while the Swedish Academy of Letters took responsibility for rewarding outstanding achievements in literature. The Swedish Medical University’s Karolinska Institute was given the task of awarding excellence in physiology and medicine, and the Peace Prize was presented to the Norwegian Parliament.
• In 1968, the economic sciences prize was awarded on the initiative of the Swedish Central Bank. The bank generously donated the prize to the Nobel Foundation, which handed over its management to the Royal Swedish Academy of Sciences.

Although some critics argue that the Economics Prize does not actually meet its original purpose, it continues to be awarded along with other prestigious awards.
