The goal of attosecond 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 is to extract isolated attosecond pulses from the pulse trains.

These pulses can be used to provide images of processes inside atoms and molecules that occur at attosecond time scales.

E. E. "Doc" Smith would use that concept to make a technobabble explanation for a phoney-baloney scifi faster-than-light starship.

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 valleys, i.e., pulses.

Pierre Agostini and his team created trains of light pulses at 250 as.

Ferenc Krausz and his group developed techniques to select single 650 as pulses.

@AkaSci

has anyone ever looked to see if swedish or nordic scientists get a dispropotionate number of awards

at least the f*cking committe managed find a woman
