Title
(EN) METHOD AND SYSTEM OF ULTRAFAST LASER WRITING OF HIGHLY-REGULAR PERIODIC STRUCTURES
(FR) PROCÉDÉ ET SYSTÈME D'ÉCRITURE LASER ULTRARAPIDE DE STRUCTURES PÉRIODIQUES TRÈS RÉGULIÈRES
Abstract
(EN)
A method, a product by the method and device of preparation of highly-regular periodic structure using a pulsed laser beam irradiating a spot on a surface of a substrate are disclosed. The method of direct formation of highly-regular periodic structure on a materials uses activation of Surface Electromagnetic Wave (SEW) interfering with the laser beam on the surface of the substrate in a manner which ensures high quality and regularity of the obtained pattern.

La présente invention concerne un procédé, un produit obtenu par le procédé et un dispositif de préparation d'une structure périodique très régulière à l'aide d'un faisceau laser pulsé irradiant un point sur une surface d'un substrat. Le procédé de formation directe d'une structure périodique très régulière sur des matériaux utilise l'activation d'une onde électromagnétique de surface (SEW) interférant avec le faisceau laser sur la surface du substrat de manière à assurer une qualité et une régularité élevées du motif obtenu.
