COHERENT ANTI-STOKES RAMAN SCATTERING AS A LOCAL PROBE FOR NANOCOMPOSITE MATERIALS (NANOCARS)

Abstract: Diagnostic aspects of coherent anti-Stokes Raman scattering (CARS) in nanocomposite materials are analyzed. The interference nature of CARS spectra and the high spatial resolution make this nonlinear process an ideal local probe for the metrology of nanostructures and nanocomposites (nanoCARS). Coherent anti-Stokes Raman scattering (CARS) [1, 2] is one of the most powerful and convenient nonlinear-optical techniques, which has been extensively used through the past four decades for gas-phase, plasma, flame, and combustion diagnostics, investigations of energy relaxation pathways in molecular systems, and high-resolution spectroscopy. More recent advances in CARS includ
