Abstract
(EN)
A method of removing from the surface of an object a contaminating substance buried in an organic substance on the surface of the object, the method including directing a laser beam at the organic substance to cause chemical change of the organic material or direct removal of the organic material by laser generated chemical change.
(FR)
Procédé consistant à enlever de la surface d'un objet une substance contaminante enfouie dans une substance organique de ladite surface, en dirigeant un rayon laser sur la substance organique afin de provoquer une modification chimique du matériau organique ou l'éjection directe de ce matériau au moyen de la modification chimique générée par le laser.
