METHOD FOR COATING AN OPTICAL COMPONENT FOR A LASER ARRANGEMENT AND RELATED OPTICAL COMPONENT
First Claim
1. A method, comprising:
- providing an optical component, a surface of the optical component being formed with parallel, periodically structured surface sections, each surface section having a first flank and a second flank, the first and second flanks of each surface section being inclined with respect to one another, and the first flank of each surface section being smaller than the second flank of the surface section; and
applying a coating to at least part of the first flank of each surface section, the coating including a metal layer and a dielectric multilayer, the metal layer being applied before the dielectric multilayer, and the second flank being uncoated or coated with a layer thickness that is smaller than a layer thickness of the coating of the first flank.

Abstract
A method for coating an optical component comprises providing the optical component. The optical component has a surface formed with parallel, periodically structured surface sections each having a first flank and a second flank. The first flank and the second flank of each surface section are furthermore inclined with respect to one another, and the first flank is formed such that it is smaller than the second flank. The method furthermore comprises at least partly applying a coating to at least the first flank of each surface section. The surface coating has a metal layer and a dielectric multilayer and the metal layer is applied before the dielectric multilayer. The second flank is not coated or is coated with a layer thickness that is formed such that it is smaller than a layer thickness of the surface coating of the first flank.
