Aims
The general learning objective of the course is to acquire theoretical and practical skills of a master in "Laser material processing", in order to be able to:
(a) start (applied) research in the field of laser-materials processing (e.g. a Master-assignment),  (b) apply laser sources/equipment as a tool in research and industry. More specifically, after the course the student is able to:
  1. explain how laser radiation is generated, and what the characteristics are of laser radiation and laser beams,
  2. choose/select/compile components which make up a laser-processing system (source, optics, manipulator, peripherals, etc) for a given laser-application (cutting, welding, etc.)
  3. describe the advantages and characteristics (incl. physical phenomena) of the different laser-material processing technologies (processes),
  4. calculate/estimate the effect of quantities (laser parameters, processing parameters, ..) on the processing result,
  5. determine optimal laser processing conditions experimentally,
  6. demonstrate awareness of the safety risks and safety measures involved when working with laser (sources) in the  practical assignments,
  7. exploit the benefits of the laser for materials processing, by suggesting a (re)design of products to be laser-machined,
  8. name the components of a real-time controller for laser materials processing,
  9. calculate the costs of laser materials processing.
Content
Course description/ contents:
This course addresses the use of high (average) power laser sources (typically 50W and more) for the processing of materials (mainly metals). After an introduction to the generation and properties of laser radiation, laser sources, and physical phenomena governing laser-material interaction (absorption, heat transfer, etc.), the course focusses on the use, advantages and benefits of the laser as a production tool. Not only, conventional processes like laser-cutting, -welding and surface treatment are discussed, but also relatively new processes like micro-processing, on micro- and nano-meter scale using ultra short laser pulsed (in the femto- and picosecond regime) are studied. To fully exploit the advantages of the laser as a production tool, an existing product might need to be redesigned Therefore the concept of “Design for Laser” is addressed in this course. The laser(source) and laser-material-processing are highly flexible, allowing a high degree of automation. Therefore process-control (real-time feedback) is discussed. Practical assignments, in which small groups of students work on experiments with state-of-the-art high-power laser workstations, are part of the course.
