Reports on Physics Research Findings from Federal University Provide New Insights (Effect of pulses from a high-power ytterbium fiber laser on a material with a nonuniform refractive index. II. Production and parameters of Nd:Y2O3 nanopowders)

By a News Reporter-Staff News Editor at Physics Week -- A new study on Physics Research is now available. According to news reporting originating in Ekaterinburg, Russia, by VerticalNews journalists, research stated, "The laser ablation of the Nd:Y2O3 target with substantially nonuniform refractive index leads to the formation of a needle-shaped surface with a needle height of 6-8 mm."

The news reporters obtained a quote from the research from Federal University, "An increase in the displacement velocity of the laser beam on the surface to 80 cm/s and an increase in the diameter of the laser spot at the central part of the beam waist to 430 mu m lead to a more uniform relief of the target surface and an increase in the nanopowder yield and production rate to 22% and 23 g/h, respectively. In addition, an excess of the mole content of the low-melting Nd2O3 in the powder decreases from 174 to 11% in comparison with the target."

According to the news reporters, the research concluded: "At an air pressure in the evaporation chamber of 0.8 bar, the mean sizes of nanoparticles (13-14 nm) are virtually independent of the displacement velocity of the beam on the surface (7-81 cm/s) and the rate of air flow above the target (13-70 m/s) in spite of significantly different nanopowder production rates."
