Abstract
Considerable interest are the studies related to the influence of powerful energy flows of natural gold-dispersed mineral medium, since such investigations lead to a new decision of technological problems of mineral processing. In this paper nonlinear effects occurring as a result of experimental studies using an ytterbium fiber laser source LS-06, with a wavelength 1060 nm, continuous action are studied. It was carried out modeling of these processes. Natural samples containing submicron gold were investigated, with identified local orderliness of ultrafine particles of gold. Observed ultrafast nonlinear processes are an open non-equilibrium system in the interaction of laser radiation with matter. The laser radiation can provide high speed local temperature changes in the material that leads to thermal strong interaction, concentration, charge and other streams. The possibility of integration of the noble metal particles in the processing of laser radiation with regard to the properties of gold dispersed samples is proved. Effectiveness of submicron gold laser sintering depends on the temperature distribution in the irradiated sample, which is determined by the parameters of laser radiation.
