Self-referenced spectral interferometry cross-checked with SPIDER on sub-15 fs pulses

We characterized 11.7 fs nearly perfect Fourier Transform pulses with self-referenced spectral interferometry (SRSI), a new recently demonstrated technique. These pulses were first precisely optimized with three feedback loops between the SRSI setup and an AOPDF. An inherent control criterion to confirm that the measurement quality is theoretically derived and experimentally demonstrated. Each experimental result was cross-checked with SPIDER.
