Abstract
We demonstrate a method for determining the phase of the third-order susceptibility, χ(3), in the proximity of a Raman resonance. The measurements were based on the phenomenon of polarization beats, which was exploited in a time-delayed four-wave-mixing experiment with bichromatic beams. The phase dispersion of χ(3) was studied close to resonance with the 655.7-cm−1 vibrational mode of carbon disulfide.Keywords
