Intracavity laser spectroscopy for the identification of nanomedia

The optical absorption and emission spectra of heterogeneous plasma formations involved in the thermal synthesis of carbon-based nanomaterials have been studied. A characteristic relationship between parameters of the plasma-assisted synthesis of carbon nanotubes (CNTs) and the spectrum of giant Raman scattering is revealed. Operation of the intracavity laser spectroscopy setup in a near-field microscopy (tip-enhanced Raman spectroscopy) regime was observed. In this regime, a CNT formed in the laser plasma plays the role of a probe capable of enhancing the intensity of emission due to the Raman scattering.
