Summary:
- Researchers have created the shortest hard X-ray laser pulses ever produced, lasting only 43 attoseconds (43 billionths of a billionth of a second).
- These ultra-short X-ray pulses can be used to study the fastest processes in nature, such as the motion of electrons within atoms and molecules.
- The development of this new laser technology represents a significant advancement in the field of ultrafast science, opening up new possibilities for exploring the fundamental dynamics of matter at the atomic and molecular scale.
