Abstract
(EN)
An ultra-short pulse laser beam (107) output from a laser (105) is diffracted into a plurality of laser beams, and a nozzle plate (155) is scanned with the laser beams at a scanning speed of 40&mgr;m/s to 300&mgr;m/s. A placement position z of the nozzle plate with respect to a direction of an optical path of each laser beam is set to be -20 &mgr;m to +25&mgr;m, where z is 0 at a reference position at which a hole diameter of the nozzle is minimum, and z increases as the placement position is moved closer to a source of the laser beam and decreases as the placement position is moved away from the source of the laser beam.

Selon l'invention, un faisceau laser à impulsion ultracourte (107) émis à partir d'un laser (105) est diffracté en une pluralité de faisceaux laser et une plaque de buses (155) est balayée au moyen des faisceaux laser à une vitesse de balayage comprise entre 40?m/s et 300?m/s. Une position de placement z de la plaque de buses par rapport à un sens d'un chemin optique de chaque faisceau laser est établie de manière à être comprise entre -20 ?m et +25?m, z étant égal à 0 au niveau d'une position de référence au niveau de laquelle le diamètre de trou de la buse est minimal et z augmentant au fur et à mesure que la position de placement est déplacée à proximité d'une source du faisceau laser et diminuant au fur et à mesure que la position de placement est éloignée de la source du faisceau laser.
