Physicists peer into ultrashort laser pulses

08 Dec 2006

Researchers in the UK have unveiled a new technique for characterizing the light within ultrashort infrared laser pulses. The method determines the phase of the light relative to the pulse envelope, and could improve scientists' ability to probe the electrons in atoms and molecules and lead to a better understanding of how chemical reactions occur (Nature Physics doi:10.1038/nphys463).

Atto boy!
Laser pulses lasting tens of femtoseconds (10-15s) are used to manipulate the electrons involved in
