Laser Processing Technology

assoc. prof. dr. Matija Jezeršek

Study materials and information on current events and assessments can be found on the student website of the Faculty of Mechanical Engineering.

Short description:

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.
