Abstract: Method for manufacturing an optical component, including a substrate made of a fusible material, includes the following steps a) and b) of steps a), b) and c), or steps a), b), c) and d): a) roughing; b) fine grinding; c) polishing; and d) finishing. The method includes steps, subsequent to any one of steps b), c) and/or d): e) inspecting the optical surface of the optical component; f) detecting and locating at least one surface defect to be eliminated; g) for each surface defect, applying a laser beam to an area emcompassing the defect, so as to produce a local remelting of the fusible material, and to form, at the location of the defect, an area of material remelted; h) polishing the optical surface including at least one area of remelted material, to produce a polished optical surface free of surface defects, and continuing with steps c) and d).

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.
