Paper Abstract

Dual color four-wave-mixing is used to visualize individual gold nanowires and single carbon nanotubes. The strong nonlinear signals, which are detected at the anti-Stokes frequency, originate from the electronic response of the nanostructures. In gold nanowires, the collective electron motions produce detectable coherent anti-Stokes signals that can be used to study the orientation and relative strength of the structure's plasmon resonances. In single walled carbon nanotubes, coherent anti-Stokes contrast can be used to map the orientation of the electronic resonances in single tubes. Coherent anti-Stokes imaging of the material's electronic response allows the first close-ups of the coherent nonlinear properties of individual structures and molecules.
