Patent number: 8720254Abstract: Micro-leaks are detected by means of a sniffer device including, in an original manner, a flat suction capsule (11) with divergent channels where the flow is regular, a resonant optical cavity (15) as a means of detection and a pump (16) with a low flow rate, which is insufficient to create a vacuum which would be required with other means of detection. Much fainter micro-leaks can be detected.Type: GrantFiled: January 6, 2010Date of Patent: May 13, 2014Assignee: Commisariat a l'Energie Atomique et aux Energies AlternativesInventors: Agnès Pailloux, Julien Cousin, Isabelle Debecker, Jean-Marc Weulersse

Publication number: 20110248005Abstract: A method of cutting a work-piece to be cut by a laser beam, in which an incident laser beam is generated that has an initial beam parameter product (BPP), given by means of a laser source, preferably an ytterbium-doped or erbium-doped fiber laser source, coupled to at least one optical fiber for conveying the beam. Said incident laser beam is brought to a focusing head comprising at least one optical focusing device. The incident laser beam is focused by means of said optical focusing device, so as to obtain a focused laser beam, and the work-piece is cut by means of the focused laser beam. According to the invention, the quality factor of the incident laser beam is adjusted or modified by means of an optical device designed to be able to modify or vary the BPP of a laser beam so as to obtain a modified focused laser beam having a modified BPP which is different from the BPP of said incident laser beam. Associated equipment for implementing said method.Type: ApplicationFiled: August 26, 2009Publication date: October 13, 2011Applicant: L'Air Liquide Societe Anonyme Pour L'Etude Et L'Exploitation Des Procedes Georges ClaudeInventors: Francis Briand, Gaia Ballerini, Isabelle Debecker, Hakim Maazaoui, Erie Verna
