Lasers are widely used for structuring metallic surfaces by ablating material. An alternative approach for laser structuring is surface structuring by laser remelting (WaveShape), which is based onthe continuous remelting of a thin surface layer usin

High-speed laser micro polishing of TiAl6V4

Autor: Christian Nüsser, Edgar Willenborg

In the present paper, laser micro polishing of TiAl6V4 is investigated with main focus on increasing the area rate by using high pulse energy. First, the influence of the laser beam size, the scanning velocity, and the track distance on the final rou

Publikováno v: Optical Manufacturing and Testing XIII.

A number of process steps that build on one another are required to manufacture optical components from glass. The polishing steps are the most time-consuming and therefore cost-intensive parts of the process chain. Low removal rates and the depth of

Non-ablative removal of sub surface damages in ground optical glass substrates by controlled melting of thin surface layers using CO2-laser radiation

Autor: Rolf Rascher, Christian Trum, Beate Schmidbauer, Manuel Jung, Edgar Willenborg

Publikováno v: Seventh European Seminar on Precision Optics Manufacturing.

The form generation of optical surfaces by grinding and mechanical polishing results in small sub surface damages in the form of micro cracks that conventionally have to be removed by further removal of the damaged surface layers. In order to reduce
