Production of Nanopowders with the Help of Fiber Laser


Article Preview

Development of an efficient technology to produce nanopowders for nanostructured materials with improved mechanical, novel electromagnetic and optical properties is still of current importance. Nanoparticles can be made by means of laser-assisted material evaporation and subsequent vapor condensation. The method provides high-purity weakly agglomerated nanopowders with narrow grain size distribution, and can be applied to various materials. However, up to these days this technique has not found wide recognition because of a low output rate and high energy consumption. This report deals with the production technology and characteristics of nanopowders produced with the help of Yb-doped fiber laser. Data for the nanopowders characteristics, as well as output rate and energy consumption are discussed in this paper. The evaporation of materials with the help of the fiber laser was proved to be an efficient method for commercial production of the fine nanopowders.
