Ma H, Gomes AS, de Araujo CB: Raman-assisted polarization beats in time-delayed four-wave mixing. Opt Lett. 1992 Aug 1;17(15):1052-4.
We demonstrate a method for determining the phase of the third-order susceptibility, chi ((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 chi ((3)) was studied close to resonance with the 655.7-cm (-1) vibrational mode of carbon disulfide. |
