Researchers Achieve the Highest Attosecond-Pulse-Train Energy Source

Attosecond pulses are essential tools for time-resolved studies of electron dynamics on their natural time scale: attoseconds (10-18 seconds). Coincidence spectroscopy and experiments with high expectations on statistics or signal-to-noise ratio, particularly in the case of solid and molecular samples in chemistry and biology, are examples of these studies, which are all gaining popularity.

Researchers Use Laser Flashes in Cancer Research

Rapid proton irradiation is a more efficient and minimally invasive treatment for cancer than X-rays. Modern proton treatment, on the other hand, necessitates huge particle accelerators, prompting researchers to look into alternate accelerator technologies such as laser systems to boost protons. In preclinical investigations, such systems are used to pave the path for the most effective radiation therapy.
