Laser Processing Technology
assoc. prof. dr. Matija Jezeršek
The mechanisms of interaction between laser light and material are introduced in the first part. Particular emphasis is given to the effects on the absorption of light in material and the conversion of light energy into heating and subsequent melting, evaporation and ionization. The second part introduces the technologies of laser drilling, cutting, welding, marking, 3D printing and microstructuring of surfaces. Furthermore, laser control systems based on optical and optodynamic principles are presented. Tutorials consist of calculus cases and laboratory research topics, where small groups work on specific research topics in the field of laser processing through a semester, thus consolidating knowledge from lectures and gaining practical skills.
The following pre-knowledge is recommended for successful study:
• Laser systems
Content (Syllabus outline):
