Title
(EN) HOLLOW-CORE FIBER BASED BROADBAND RADIATION GENERATOR WITH EXTENDED FIBER LIFETIME
(FR) GÉNÉRATEUR DE RAYONNEMENT À LARGE BANDE À BASE DE FIBRES À ÂME CREUSE AYANT UNE DURÉE DE VIE DE FIBRE PROLONGÉE
Abstract
(EN) Disclosed is an optical component for a broadband light source device, the optical component being configured for generating a broadband output upon receiving pump radiation and comprising: a hollow-core photonic crystal fiber (HC-PCF); and a gas mixture filling said HC-PCF, wherein said gas mixture comprises a mixture of at least one first gas configured for the generation of the broadband radiation and at least one second gas comprising or consisting of Helium.
(FR) L'invention concerne un élément optique destiné à un dispositif de source de lumière à large bande, l'élément optique étant conçu pour générer une sortie à large bande lors de la réception d'un rayonnement de pompage et comprenant : une fibre de cristal photonique à âme creuse (HC-PCF) ; et un mélange gazeux remplissant ladite HC-PCF, ledit mélange gazeux comprenant un mélange d'au moins un premier gaz conçu pour générer le rayonnement à large bande et d'au moins un second gaz comprenant de l'hélium ou constitué d'hélium.
