Abstract
The invention concerns a method for laser ablation of a surface coating from a wall, such as a painted wall finish, for example in a nuclear plant to be decontaminated, and a device for implementing said method. The inventive ablation method includes sweeping shots on the coating of at least one pulsed laser beam with a laser beam quality factor Mless than 20, and characterized in that it comprises a direct control of said shots by optical deflection, such that the impact zones (I, I, I,) of said shots on said coating are disjointed or substantially adjacent with minimized overlapping.
