Examinons-les s\u00e9par\u00e9ment :<\/p>\n\n\n\n<p>Le premier type de \"traitement thermique\" : il s'agit d'un faisceau laser \u00e0 haute densit\u00e9 \u00e9nerg\u00e9tique (c'est un flux d'\u00e9nergie concentr\u00e9), irradi\u00e9 sur la surface du mat\u00e9riau \u00e0 traiter, la surface du mat\u00e9riau absorbe l'\u00e9nergie laser et g\u00e9n\u00e8re un processus d'excitation thermique dans la zone irradi\u00e9e, augmentant ainsi la temp\u00e9rature de la surface du mat\u00e9riau (ou du rev\u00eatement), ce qui entra\u00eene la m\u00e9tamorphose, la fusion, l'ablation, l'\u00e9vaporation, et d'autres ph\u00e9nom\u00e8nes.<\/p>\n\n\n\n<p>Le deuxi\u00e8me type de \"traitement \u00e0 froid\" : il s'agit de photons \u00e0 tr\u00e8s haute \u00e9nergie (ultraviolets), qui peuvent rompre les liaisons chimiques dans les mat\u00e9riaux (en particulier les mat\u00e9riaux organiques) ou les milieux environnants, afin de causer des dommages non thermiques aux mat\u00e9riaux. Ce type de traitement \u00e0 froid rev\u00eat une importance particuli\u00e8re dans le traitement du marquage au laser, car il ne s'agit pas d'une ablation thermique, mais d'un pelage \u00e0 froid qui ne produit pas d'effets secondaires de \"dommages thermiques\" et qui rompt les liaisons chimiques, de sorte qu'il n'est pas nocif pour la couche interne et les zones voisines de la surface trait\u00e9e.
