Autocorrelation measurement of an attosecond pulse train

Abstract :
Direct observation of an attosecond pulse train, formed with synthesized high- order harmonic fields of an intense femtosecond pulse, is demonstrated. The two photon above-threshold ionization of an argon atom and the two-photon Coulomb explosion of a nitrogen molecule are utilized as a correlated signal of our autocorrelation measurements.
