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

Opt Lett. 2010 Nov 15;35(22):3856-8. doi: 10.1364/OL.35.003856.


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.
