The goal of attosecond laser physics is to generate light pulses that are 10s to 100s of attoseconds long from laser light which has much longer wave period (e.g., infrared light lasers with wave periods of femtoseconds). A secondary goal i
Here is video in which Nobel Laureate Ferenc Krausz of the Max Planck Institute of Quantum Optics patiently explains Attosecond Physics along with a tour of his group's lab and its complex equipment. https://www.youtube.com/watch?v=6ZIUJb85
Anne L’Huillier and her team sent infrared laser light thru a noble gas and studied high order harmonics and overtones at attosecond (as) periods generated by electron energy transitions. The blend of these harmonics created peaks and valle

every network with a public tag surfaceFollow #attosecond straight to each platform’s own tag page. Where a platform publishes open data we measure it above; the rest lock their numbers behind paid APIs, so we link rather than guess.
Every number above is measured from a named public API at the shown fetch time. Nothing is estimated or extrapolated. Platforms that lock their data behind paid APIs are not shown. Agents: the same numbers, as JSON, at /api/hashtags/attosecond
