Abstract
We show that frequency-resolved optical gating combined with spectral interferometry yields an extremely sensitive and general method for te mporal characterization of nearly arbitrarily weak ultrashort. pulses even when the reference pulses is not transform limited. We experiment ally demonstrate measurement of the full time-dependent intensity and phase of a train of pulses with an average energy of 42 zeptojoules (4 2 x 10(-21) J), or less than one photon per pulse.
