METHOD OF ABLATING A SURFACE LAYER OF A WALL, AND ASSOCIATED DEVICE

摘要

The invention relates to a method of ablating a surface layer (2) of a wall (P) by sweeping the said layer (2), comprising: a step (Ecom) of directional control by an optical deflector (5) of a plurality of pulsed laser beams (7); a step (Eab) of ablating the layer (2) on impact zones (ILC) created by the plurality of laser beams, each impact zone (ILC) being defined by a centre (C) and by a characteristic dimension (d1, d2, d3); the method is characterized in that the impact zones (ILC) are disjoint, the distance (DI) between each centre (C) of the impact zones (ILC) being equal to at least ten times the largest characteristic dimension (d1, d2, d3) of the impact zones. The invention also relates to a corresponding device.
