It is shown that frequency-resolved optical gating combined with spectral interferometry yields an extremely sensitive and general method for temporal characterization of nearly arbitrarily weak ultrashort pulses even when the reference pulses is not transform limited.Abstract:
We show that frequency-resolved optical gating combined with spectral interferometry yields an extremely sensitive and general method for temporal characterization of nearly arbitrarily weak ultrashort pulses even when the reference pulses is not transform limited. We experimentally demonstrate measurement of the full time-dependent intensity and phase of a train of pulses with an average energy of 42 zeptojoules (42 × 10−21 J), or less than one photon per pulse.read more

Characterization of ultrashort electromagnetic pulses
TL;DR: In this paper, a review of advances made in the latter field over this period, indicating the general principles involved, how these have been implemented in various experimental approaches, and how the most popular methods encode the temporal electric field of a short optical pulse in the measured signal and extract the field from the data.

Controlling the shape of a quantum wavefunction
TL;DR: In this article, a computer-controlled laser is used to excite a coherent state in atomic caesium, and the shape of the wavefunction is then measured and the information fed back into the laser control system, which reprograms the optical field.
