An apparatus and method are disclosed for removal of material from a substrate or structure using a broadband flashlamp-type radiator (200) for providing broadband radiant energy (204), an ultraviolet radiator (302), lamp head or other focusing means (212) for directing the broadband radiant energy (204) and ultraviolet radiant energy (306) onto the surface of the coating or coatings or other material to be removed, thereby resulting in the ablation and photodissociation of the material, and a residual constituents removing means (108), such as flowing CO2 pellets, liquid CO2, jets of compressed air, particles or other flowing gases or liquids.

L'invention concerne un procédé et un dispositif pour éliminer un matériau présent sur un substrat ou une structure au moyen d'un élément rayonnant (200), de type lampe-éclair à large bande, qui produit une énergie rayonnante à large bande (204), d'un élément produisant des rayonnements UV (302), d'une tête de lampe ou autres moyens de focalisation (212) pour diriger l'énergie rayonnante à large bande (204) et l'énergie de rayonnement UV (306) sur la surface du ou des revêtements ou autres matériaux à éliminer, ce qui permet l'ablation et la photodissociation du matériau. Ledit dispositif comprend également des moyens (108) pour éliminer les constituants résiduels, par exemple des pastilles de CO¿2? à écoulement, du CO¿2? liquide, des jets d'air comprimé, des particules ou d'autres gaz ou liquides à écoulement.
