Dual-chirped Methodology Enables High-grade Attosecond Imaging
SENDAI, Japan, May 9, 2024 — Extremely short laser pulses, in the order of attoseconds, provide a powerful way to probe and image ultrashort processes like the motion of electrons in atoms and molecules. While it is possible to create ultrashort laser pulses, creating pulses that are both ultrashort and high-energy is a persistent challenge. To scale up the photon energy, photon flux, and continuum bandwidth for isolated attosecond pulses, it is necessary to develop a stable, high-energy, single-cycle laser source
