Single-shot, high-dynamic-range measurement of sub-15 fs pulses by self-referenced spectral interferometry

We explore theoretically and numerically the temporal contrast limitation of a self-referenced spectral interferometry measurement. An experimental confirmation is given by characterization and fine compression of hollow-core fiber generated sub-15 fs pulses, yielding an accurately measured coherent contrast of 50 dB on a +/- 400 fs time range.
