LASER DECONTAMINATION METHOD

摘要

A method for the removal of embedded contamination from a metallic surface in which a laser beam is directed onto the contaminated surface. The laser beam has sufficient power density to cause direct ejection of laser-generated melt pool liquid from the metallic surface thereby removing a metallic surface layer containing the embedded contamination. Means are provided for the collection of laser ejected material in order to prevent recontamination of the metallic surface or contamination of previously uncontaminated surfaces.
