Abstract
The propagation of nanosecond laser pulses in solutions of large-scale carbon nanostructures has been theoretically and numerically investigated in this paper. The three-level ladder-type scheme was used to study the medium with RSA. Numerical simulation of the propagation of nanosecond laser pulses in RSA media was carried out using the classical transport equation for incoherent nonlinear interaction of radiation with the medium described by the proposed three-level model. It is shown that for sufficiently small relaxation times of the medium and high intensity of, a splitting of the transmitted pulse by two is possible.
