Content

Based on the description of the physical basics about the formation and the properties of laser light the lecture goes through the different types of laser beam sources used in industry these days. The lecture focuses on the usage of lasers especially in materials engineering. Other areas like measurement technology or medical applications are also mentioned.

  • physical basics of laser technology
  • laser beam sources (solid state, diode, gas, liquid and other lasers)
  • beam properties, guiding and shaping
  • lasers in materials processing
  • lasers in measurement technology
  • lasers for medical applications
  • savety aspects

The lecture is complemented by a tutorial.

The student

  • can explain the principles of light generation, the conditions for light amplification as well as the basic structure and function of different laser sources.
  • can describe the influence of laser, material and process parameters for the most important methods of laser-based materials processing and choose laser sources suitable for specific applications.
  • can illustrate the possible applications of laser sources in measurement and medicine technology
  • can explain the requirements for safe handling of laser radiation and for the design of safe laser systems.

Basic knowledge of physics, chemistry and material science is assumed.

regular attendance: 33,5 hours
self-study: 116,5 hours

The assessment consists of an oral exam (ca. 30 min) taking place at the agreed date (according to Section 4(2), 2 of the examination regulation). The re-examination is offered upon agreement.

It is allowed to select only one of the lectures "Laser in automotive engineering" (2182642) or "Physical basics of laser technology" (2181612) during the Bachelor and Master studies.
