In this work we investigate the role of exciton resonances in coherentanti-Stokes Raman scattering (er-CARS) in single walled carbon nanotubes(SWCNTs). We drive the nanotube system in simultaneous phonon and excitonicresonances, where we observe a superior enhancement by orders of magnitudeexceeding non-resonant cases. We investigated the resonant effects in five$(n,m)$ chiralities and find that the er-CARS intensity varies drasticallybetween different nanotube species. The experimental results are compared witha perturbation theory model. Finally, we show that such giant resonantnon-linear signals enable rapid mapping and local heating of individualizedCNTs, suggesting easy tracking of CNTs for future nanotoxology studies andtherapeutic application in biological tissues.
