Abstract: The generation of micro– and nanoparticles using laser cutting of steel strips of the thickness of 0.2–0.6 mm and the separation of particles according to their size were studied. Under optimal cutting con ditions (laser power, gas pressure before the nozzle), the cutting quality is good when a small amount of fully oxidized erosion products at the cut edge of a slit is obtained. The study showed that the cascade filter system can be used to separate the particles up to nanometer dimensions. The simulation of the gas flow can be used to create optimal conditions for collecting generated particles of the required dimensions. The modelling data confirmed that small particles from the liquid metal state in the cut slit are generated most effectively using nozzles forming ring flows. The larger particles modification with aluminium and zinc by milling was per formed
