TLDR
In this paper, a multiplex CARS scheme was used to study the bulk polymers poly-(methyl methacrylate) (PMMA) and poly-(vinyl toluene) (PVT).Abstract:
A multiplex CARS scheme is used to study the bulk polymers poly-(methyl methacrylate) (PMMA) and poly-(vinyl toluene) (PVT). A coherent signal resulting from optical four-wave mixing is obtained with electronic and Raman-resonant parts. The magnitude of the third-order optical susceptibility tensor of these polymers is experimentally estimated. Significant enhancement of the total susceptibility by the Raman resonances is observed for PVT.read more

TL;DR: In this paper, it was argued that the large value of χ(3) is due to a three-photon resonance at 1.064 μm, and the measured average value of cubic susceptibility is equal to (1.5±0.1)×10−12 esu at 1.064 µm.
