Summary

The physical principles of laser light materials interactions are introduced with a large number of industrial application examples. Materials processing lasers are developing further and further, the lecture presents the physical limitations of the processes.

Content

1. Basics of laser processing

Lasers for machining, Optics - beam steering systems, beam quality; Optical properties of materials, Heat equation, Applications - and examples:

Laser induced chemical reactions at surfaces for marking applications,

laser bending,

hole drilling,

laser cutting,

laser induced ablation,

gnerative processes

Keywords

laser, efficiency, beam quality, spot size, laser pulse duration, heat equation, losses, machining, marking, bending, drilling, cutting, ablation, generative processing, selective laser sintering, selective laser melting
