Laser-induced nonlinear optical processes in fluid systems with nanocarbon
We report on nonlinear optical transmission in aqueous polymer suspensions of 1D, 2D and 3D carbon nanoparticles of quasi-continuous, fs- and ns-pulse laser irradiation in visible and NIR ranges. Fast processes leading to the optical limiting behavior are studied with regard to nanoparticles’ individuality, degree of aggregation and sizes.
