Laser Material Processing

Content

Based on a short description of the physical basics of laser technology the lecture reviews the most important high power lasers and their various applications in automotive engineering. Furthermore the application of laser light in metrology and safety aspects will be addressed.

  • physical basics of laser technology
  • laser beam sources (Nd:YAG-, CO2-, high power diode-laser)
  • beam properties, guiding and shaping
  • basics of materials processing with lasers
  • laser applications in material processing
  • savety aspects

The student

  • can explain the principles of light generation, the conditions for light amplification as well as the basic structure and function of Nd:YAG-, CO2- and high power diode-laser sources.
  • can describe the most important methods of laser-based processing in automotive engineering and illustrate the influence of laser, material and process parameters
  • can analyse manufacturing problems and is able to choose a suitable laser source and process parameters.
  • 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.

It is not possible, to combine this lecture with the lecture Physical basics of laser technology [2181612].
