Osipov, V. Lisenkov, V. Platonov] In this paper, the possibility of composite nanopowders production using laser evaporation method has been investigated. For this purpose, the three-dimensional thermohydrodynamical model of interaction process between the substance and laser radiation was developed. With its help, the dynamics of evaporation, movement, and crystallization of melt in Nd3+:Y3Al5O12 target have been investigated numerically. It has been established that the difference between vapor and target compositions is caused by more intensive evaporation of the components with lower boiling temperature and displacement of melt under the vapor overpressure. This difference has been obtained as a result of calculations. For the first time, the composite nanopowders in certain stoichiometric ratio have been obtained via the usage of long pulses (>300 μs). This synthesis had high productivity (>20g/h). The Nd3+:Y3Al5O12 high transparent ceramics have been obtained after the compaction of these nanopowders and vacuum sintering of the compacts at 1700°C.
