Master Thesis and/or Student Project “Simulation of laser-based lighting systems”

The Laser Zentrum Hannover e.V. (LZH) is a leading institute in the field of applied laser research. Approximately 250 employees carry out basic and applied research and develop solutions for industry. The Optical Systems Group of our Laser Development Department invites applications for a

Master Thesis and/or Student Project “Simulation of laser-based lighting systems”
Discipline/branch of study Physics, Optical Technologies, Mechanical Engineering or related disciplines with a focus on Modeling/Simulation of Optical Systems

Laser-based lighting systems are the latest development in solid-state lighting, a technology that revolutionized the illumination industry. Their applications range from automotive headlamps and tail lights to imaging and display devices such as multimedia projectors. Laser-based lighting systems usually consist of a blue- or UV-emitting laser diode combined with an appropriate phosphor layer. The white light sources produced can achieve significantly higher luminance that exceeds even the brightest LEDs. However, the efficiency of these systems has yet to be optimized. To that end, the development of a simulation strategy that investigates the limitations and calculates the optimization parameters of such systems is an invaluable tool for designing the next-generation lighting devices.

The Optical Systems Group is mainly concerned with components for modifying and modulating laser light. The scientists in the group are developing and characterizing active and passive optical components to amplify laser light, or to shape the light between the laser aperture and a workpiece. The experimental work is complemented by simulation of light propagation, taking into account the optical, thermodynamic and mechanical characteristics of the materials.

The topic of the master thesis and/or student project is flexible. The general guidelines are given below:

Main tasks:

  • Development of a ray tracing tool
  • Modeling the optical properties of a laser diode
  • Simulation of optical systems for lighting applications


  • Interest in the inner workings of optical systems for lighting applications
  • A good understanding of ray and wave optics
  • Programming skills (preferably Python or Matlab)
  • Creativity and team spirit

Starting date:

As soon as possible.

Severely disabled applicants with equal qualification will be given particular consideration.

The LZH emphasizes the professional equality between women and men.
