Attosecond pulses

Attosecond pulses are extremely brief bursts of light lasting less than a quintillionth of a second (10^-18 seconds). They allow scientists to observe and study events at the atomic and subatomic level, such as how electrons move and interact within atoms. This ultrafast timing is achieved using advanced laser techniques, enabling insights into fundamental physical processes that happen incredibly quickly. In essence, attosecond pulses act like super-fast strobe lights, illuminating the tiniest, fastest movements in nature.
