The CARS spectral profile under these conditions is controlled by the interference of the resonant part of the nonlinear-optical susceptibility, related to nitrogen molecules in the pores of aerogel, and the nonresonant contribution, provided by the mesoporous host. Raman-active vibrations of gas-phase molecular nitrogen give rise to intense resonances in CARS spectra. These spectral profiles can serve as a local probe for measuring effective-medium parameters of nanocomposite materials (nanoCARS).en1555-661120041113821385IOP Publ.PhysikJournal ArticleOther
