Abstract
The invention relates to 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 emitted by at least one injector, wherein the laser is followed by an optical device allowing the energy of the beam to be distributed along an axis perpendicular to the axis of the flow of reagents, in an elongated cross-section with adjustable dimensions at least at one interaction area between this beam and the flow of reagents emitted by at least two injectors located perpendicularly to the axis of the beam. It also concerns a method for producing such powders.
