Abstract
The intensity and phase of femtosecond pulses can be retrieved from measurements of third-order intensity correlations and the pulse spectrum using a numerical algorithm. Unbalancing the interferometer makes the retrieval algorithm sensitive to the direction of time, and improves the retrieval of certain pulse shapes. The sensitivity of the retrieval to direction of time as a function of the degree of imbalance in the correlator is investigated.KeywordsFemtosecond PulseRetrieval AlgorithmIntensity CorrelationPulse SpectrumSpectral PhaseThese keywords were added by machine and not by the authors. This process is experimental and the keywords may be updated as the learning algorithm improves.
