ABSTRACT:
The duration or pulse width of an ultrashort laser pulse is measured by disposing a nozzle in a vacuum, intermittently or continuously jetting an atomic or molecular gas beam from the nozzle, directing ultrashort laser pulses to be measured into the beam to produce harmonic radiation of the laser pulse in the gas beam or produce ions by absorption of multiple laser photons, and detecting a signal related to the harmonic or the ions.
