Self-referenced spectral interferometry for ultra-short infrared pulse characterization

Abstract

Self-Referenced Spectral Interferometry is used for single shot pulse characterization over the 0.9-2.5 µm spectral range with a single spectrometer and an optimized optical setup. We characterize sub-55 fs pulses from 1.4 µm to 2 µm and broadband 2.5-cycle pulses at 1.65 µm (13 fs FWHM).
