MSE Master of Science in Engineering

The Swiss engineering master's degree

Each module contains 3 ECTS. You choose a total of 10 modules/30 ECTS in the following module categories: 

  • 12-15 ECTS in technical scientific modules (TSM)
    TSM modules teach profile-specific specialist skills and supplement the decentralised specialisation modules.
  • 9-12 ECTS in fundamental theoretical principles modules (FTP)
    FTP modules deal with theoretical fundamentals such as higher mathematics, physics, information theory, chemistry, etc. They will teach more detailed, abstract scientific knowledge and help you to bridge the gap between abstraction and application that is so important for innovation.
  • 6-9 ECTS in context modules (CM)
    CM modules will impart additional skills in areas such as technology management, business administration, communication, project management, patent law, contract law, etc.

In the module description (download pdf) you find the entire language information per module divided into the following categories:

  • instruction
  • documentation
  • examination 
Laser and laser applications (TSM_Laser)

TSM module “Laser and Laser applications” provides a broad overview about the fascinating field of state-of-the-art Laser technology and its applications in industry, R&D, medicine and communication. The modul provides a comprehensive insight into the Laser and applications market, Laser types and devices, Beam deliveries, Laser machines, Physics of interaction between laser and material, and real industrial application examples presented by experts with industrial background.  Module objective is to increase and enhance the technological competences on laser generation, control, and laser-material interaction.physical/ technological limits and competing technology.

Prerequisites

Optics: Basics of wave and geometrical optics; without optics basics during bachelor studies, the EVA "Fundamentals of light" should be visited before visiting further TSM modules.
Physics: Basics for engineers (bachelor niveau)

Learning Objectives

After successfully completing this course the student:

  • knows the concepts of the most important laser types with their respective advantages and disadvantages and will be informed about future trends.
  • will be skilled to decide between Laser-based technology or other manufacturing technology based on knowledge in technology, efficiency, economical, and ecological reasons
  • knows industrial relevant beam guiding and delivery systems and technologies
  • will be skilled to make decision on suitable laser source and beam delivery depending on application process.
  • thoroughly understands important laser applications and can design the most relevant features of the systems required for them
  • knows the most relevant physical effects which happen during the interaction between laser and material
  • will be skilled to determine processing strategy, basic parameters and supporting technology 
  • knows basics methods of beam diagnostics, process monitoring, and industry 4.0 technology
