L’invention concerne un dispositif (DS) de synthèse de nanoparticules par pyrolyse laser, caractérisé en ce qu’il comporte : au moins un réacteur (R) se présentant sous la forme d’une conduite munie d’un axe longitudinal (X0), le réacteur (R) comprenant, à une première extrémité (PE), une première fenêtre (FE) pour un faisceau laser (FL) et, à une deuxième extrémité (DE) opposée à la première extrémité selon l’axe longitudinal (X0) du réacteur (R), une deuxième fenêtre (FS) pour le faisceau laser (FL) ;un dispositif optique (DO) comprenant un laser (L) agencé pour émettre un faisceau laser (FL) apte à se propager dans le réacteur (R) depuis la première fenêtre (FE) vers la deuxième fenêtre (FS) selon la direction définie par l’axe longitudinal (X0) du réacteur (R) ;au moins un premier canal (PC) débouchant dans le réacteur (R) au niveau d’une entrée (EP) de réacteur, le premier canal (PC), muni d’un axe longitudinal (X1), étant agencé de sorte que son axe longitudinal (X1) définisse, avec l’axe longitudinal (X0) du réacteur (R), un angle A01 aigu mais non nul, ainsi qu’un deuxième canal (DC) sortant du réacteur (R) au niveau d’une sortie (SNP) de réacteur ; le premier canal (PC) étant ainsi apte à amener dans le réacteur (R), pour synthétiser les nanoparticules par pyrolyse laser, un flux de gaz porteur comportant au moins un précurseur de nanoparticules apte à interagir colinéairement avec le faisceau laser (FL) le long de l’axe longitudinal (X0) du réacteur (R) entre l’entrée (EP) et la sortie (SNP) du réacteur et le deuxième canal (DC) étant alors apte à récupérer les nanoparticules ainsi formées par pyrolyse laser dans le flux de gaz porteur. Figure pour l’abrégé : Figure 1.TITLE: Device for collinear synthesis of nanoparticles by laser pyrolysis, associated system and process. The invention relates to a device (DS) for synthesizing nanoparticles by laser pyrolysis, characterized in that it comprises: at least one reactor (R) in the form of a pipe provided with a longitudinal axis (X0) , the reactor (R) comprising, at a first end (PE), a first window (FE) for a laser beam (FL) and, at a second end (DE) opposite the first end along the longitudinal axis (X0 ) of the reactor (R), a second window (FS) for the laser beam (FL);an optical device (DO) comprising a laser (L) arranged to emit a laser beam (FL) able to propagate in the reactor ( R) from the first window (FE) towards the second window (FS) along the direction defined by the longitudinal axis (X0) of the reactor (R);at least one first channel (PC) opening into the reactor (R) at the level of a reactor inlet (EP), the first channel (PC), provided with a longitudinal axis (X1), being arranged so that its longitudinal axis (X1) defines, with the longitudinal axis (X0) of the reactor (R), an acute but non-zero angle A01, as well as a second channel (DC) exiting the reactor (R) at a reactor outlet (SNP); the first channel (PC) thus being capable of bringing into the reactor (R), in order to synthesize the nanoparticles by laser pyrolysis, a flow of carrier gas comprising at least one precursor of nanoparticles capable of interacting collinearly with the laser beam (FL) the along the longitudinal axis (X0) of the reactor (R) between the inlet (EP) and the outlet (SNP) of the reactor and the second channel (DC) then being able to recover the nanoparticles thus formed by laser pyrolysis in the carrier gas flow.
