Scientists Find Way to Keep Ultra-Fast Light Flashes Intact

Topic: Physics

Researchers at Skoltech and Shanghai Institute of Optics found a way to preserve ultra-fast light pulses, called attosecond flashes. These flashes can 'freeze' the motion of electrons and help study atoms, molecules, and solids. The team created a map to determine the right target thickness for these experiments.

Scientists at Skoltech in Russia and Shanghai Institute of Optics and Fine Mechanics in China have made an important discovery about ultra-fast light pulses called attosecond flashes. An attosecond is one quintillionth of a second, which is incredibly short – shorter than the time it takes for light to travel from the Earth to the Moon! These flashes can be compared to a very short camera flash that helps capture fast-moving objects clearly.

The researchers used powerful computers and simulations to figure out how to keep these attosecond flashes intact. They found that when these pulses pass through plasma (a gas-like state of matter), they can get distorted if the plasma is too thick or dense. This distortion makes it difficult to study ultra-fast processes in atoms, molecules, and solids.

The team created a map that shows which target parameters will preserve the attosecond structure of the pulse and which ones will cause it to break down. This map will help researchers choose the right experimental parameters and avoid wasting time on trial-and-error simulations. The findings will also improve the design of plasma-based sources of ultraviolet and X-ray radiation used in scientific research.
