Summary:The subject of the present invention is a device for treating a surface or a zone using a laser beam comprising a laser treatment head (1) comprising a housing (2), a system generating or receiving a power laser beam (3), an optical collimation system (4), an optical focusing system, the said housing (2) comprising a frontal side (2a) in which there is made a frontal opening (2b) to let out the laser beam passing through the said focusing system (4) into the said housing. It further comprises a thermal hold system (7) allowing the temperature of the interior space of the housing to be maintained and comprising a frontal thermal hold plate (7a) pressed against the external face of the frontal side (2a) or incorporated into, or forming, the said frontal side (2a), at least in part. La présente invention a pour objet un dispositif de traitement d'une surface ou d'une zone par faisceau laser comprenant une tête (1) de traitement au laser comprenant un boîtier (2), un système générateur ou récepteur d'un faisceau laser de puissance (3), un système optique de collimation (4), un système optique de focalisation, ledit boîtier (2) comportant un côté frontal (2a) dans lequel est pratiquée une ouverture frontale (2b) permettant la sortie du faisceau laser traversant ledit système de focalisation (4) dans ledit boîtier. Il comprend en outre un système de maintien thermique (7) permettant un maintien thermique de l'espace intérieur du boîtier et comprenant une plaque de maintien thermique (7a) frontale appliquée contre la face externe du côté frontal (2a) ou intégrée dans, ou formant, au moins en partie ledit côté frontal (2a).
