Abstract: A method for the corrective treatment of a defect on the surface of an optical component for a power laser, includes a first step of applying a first laser beam having a power P1 for a duration t1 so as to generate an illumination E1 on a first zone, the size and position of which match the defect to be corrected, the first laser beam having a wavelength ? that can be absorbed by the material of the optical component in order to form a crater on the surface of the optical component. The method includes a second step of applying a second laser beam having a power P2 for a duration t2 on a second zone including at least the periphery of the crater created during the first step in order to subject the second zone to an illumination E2 that is lower than the illumination E1.
