System And Method For Continuous Flow Production of Nanometric Or Sub-Micrometric Powders By The Action of Laser Pyrolysis

A system for continuous flow production of nanometric or sub-micrometric powders under the action of laser pyrolysis by interaction between a beam emitted by a laser and a flow of reagents, wherein the laser is followed by an optical device allowing the energy of the beam to be distributed independently along either one of the axes perpendicular to the axis of propagation of the beam in an elongated cross-section with adjustable dimensions at several interaction areas between this beam and flows of reagents emitted, in each interaction area, by at least two injectors located perpendicularly to the axis of the beam so that the flows of reagents exiting from these at least two injectors are all covered by the elongated cross-section of the beam.
