Title (EN) LASER IGNITION DEVICE AND OPERATING METHOD FOR SAME
(FR) DISPOSITIF D'ALLUMAGE PAR LASER ET SON PROCÉDÉ DE FONCTIONNEMENT
(DE) LASERZÜNDEINRICHTUNG UND BETRIEBSVERFAHREN HIERFÜR
Abstract:
(EN) The invention relates to a method for operating a laser ignition device for an internal combustion engine (10), particularly of a motor vehicle, wherein a plurality of different laser beams (24a, 24b, 24c, 24d) are generated and combined with each other, particularly bundled to a common focal point (FP). According to the invention, all the laser beams (24a, 24b, 24c, 24d) are generated within a laser-active solid body (44).
(FR) L'invention concerne un procédé de fonctionnement de dispositif d'allumage par laser pour moteur à combustion interne (10), en particulier de véhicule automobile, qui produit et combine entre eux plusieurs faisceaux laser différents (24a, 24b, 24c, 24d), en particulier concentrés sur un point focal commun. Selon l'invention, tous les faisceaux laser (24a, 24b, 24c, 24d) sont produits à l'intérieur d'un corps solide à activité laser (44).
(DE) Die Erfindung betrifft ein Verfahren zum Betreiben einer Laserzündeinrichtung für eine Brennkraftmaschine (10), insbesondere eines Kraftfahrzeugs, bei dem mehrere unterschiedliche Laserstrahlen (24a, 24b, 24c, 24d) erzeugt und miteinander kombiniert, insbesondere auf einen gemeinsamen Fokuspunkt (FP) gebündelt, werden. Erfindungsgemäß werden alle Laserstrahlen (24a, 24b, 24c, 24d) innerhalb eines laseraktiven Festkörpers (44) erzeugt.
