Self-referenced spectral interferometry for ultrashort infrared pulse characterization

Opt Lett. 2012 Jul 15;37(14):2892-4. doi: 10.1364/OL.37.002892.

Abstract

We demonstrate for the first time (to our knowledge) characterization of ultrashort IR pulses by self-referenced spectral interferometry. Both sub-55-fs pulses from 1.4 μm to 2 μm and broadband 2.5-cycle pulses at 1.65 μm (13 fs FWHM) are characterized.
