MSE Master of Science in Engineering

The Swiss engineering master's degree

Ogni modulo equivale a 3 crediti ECTS. È possibile scegliere un totale di 10 moduli/30 ECTS nelle seguenti categorie: 

  • 12-15 crediti ECTS in moduli tecnico-scientifici (TSM)
    I moduli TSM trasmettono competenze tecniche specifiche del profilo e si integrano ai moduli di approfondimento decentralizzati.
  • 9-12 crediti ECTS in basi teoriche ampliate (FTP)
    I moduli FTP trattano principalmente basi teoriche come la matematica, la fisica, la teoria dell’informazione, la chimica ecc. I moduli ampliano la competenza scientifica dello studente e contribuiscono a creare un importante sinergia tra i concetti astratti e l’applicazione fondamentale per l’innovazione 
  • 6-9 crediti ECTS in moduli di contesto (CM)
    I moduli CM trasmettono competenze supplementari in settori quali gestione delle tecnologie, economia aziendale, comunicazione, gestione dei progetti, diritto dei brevetti, diritto contrattuale ecc.

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.

Requisiti

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)
