Paper Abstract

We extend the Frequency-Resolved Optical Gating (FROG) technique to the measurement of the time-dependent intensity and phase of arbitrary ultraweak ultrashort pulses. We accomplish this by combining FROG with spectral interferometry. Spectral interferometry (SI) yields the phase difference between an unknown and a known pulse (the latter characterized with FROG). SI is a linear-optical method and hence is very sensitive. We demonstrate the combination of these two techniques by measuring the intensity and phase of a train of pulses 42 zeptojoules in energy (1/5 of a photon per pulse).
