Publication date: 2017 Source:Physics Procedia, Volume 86 Author(s): A.Yu. Mayor, D.Yu. Proschenko, S.S. Golik, I.V. Postnova, Yu.A. Shchipunov, A.A. Podlesnyh Experimentally studied linear and nonlinear characteristics of colloid on the basis of a new class of carbon nanoparticles (CN) synthesized by hydrothermal synthesis. The spectral characteristics of supercontinuum of the colloids with CN in the range 420 - 700nm were investigated. The effectiveness of excitation of one- and two-photon fluorescence colloids with UN was determined. The anomalous dependence of the nonlinear refractive index of the wavelength of the radiation was revealed. It was installed that the efficiency of spectral transformation of the supercontinuum process in the case of colloid with carbon nanoparticles is less in the anti-stokes region than in case with water.
