The focused IR laser beam heats the damage site to a predetermined peak temperature, which melts and reflows material at the damage site of the optical material to create a mitigated site.

Abstract: A molding is produced with a disk-shaped or plate-shaped basic body having a large number of knob-like and/or web-like elevations which merge into the basic body with inclined side surfaces. The molding is produced by pressing and sintering powdery raw materials close to the final shape. First, the boundary surfaces of the basic body are pressed to final shape as far as the transition regions of the elevations and the elevations are pressed to an oversize. The projection height of the elevations from the basic body is greater than the projection height in the finally pressed state. Their side surfaces form an angle of inclination in the range from 90°-150° with the respectively adjacent boundary surface of the basic body. Then the elevations are pressed to near final shape while the angle of inclination is enlarged to a greater value.
