The IR laser-induced radiation of carbon materials is experimentally investigated. The broadband spectra of radiation in the visible region, as well as the redshift of the spectra of dispersed carbon materials relative to the spectra of bulk polycrystalline graphite, have been found. All measured spectra are typical for incoherent dipole radiation. Broadband radiation is qualitatively explained by Raman scattering of photons.
