Abstract
The invention relates to a method of ablating a surface layer of a wall by sweeping the said layer, comprising: a step of directional control by an optical deflector of a plurality of pulsed laser beams; a step of ablating the layer on impact zones created by the plurality of laser beams, each impact zone being defined by a centre and by a characteristic dimension; the method is characterized in that the impact zones are disjoint, the distance between each centre of the impact zones being equal to at least ten times the largest characteristic dimension of the impact zones. The invention also relates to a corresponding device.
