Laser Technology
The use of lasers in illumination systems is appropriate if maximum light output or special lighting effects are to be achieved. Examples are light sources of very high luminance by blue laser diodes that are used as an excitation source in converter modules. In effect or stage lighting, the low beam divergence of rgb lasers is a key feature. Lasers are particularly suited in applications with optical fibers, since the usage of laser light enables efficient coupling. We are using the latest laser diode technologies, laser collimation know-how and long-term expertise in thermal and mechanical design to realize cutting-edge and innovative laser systems.

Radially Emitting Fiber Modules
For special lighting effects, a light module was developed in which laser diode light is coupled into radially emitting light fibers. A particular focus in the development of such side-emitting fiber systems is the selection and testing of the correct fiber cross-sections, for optimal bending and lighting results. The optical layout of an efficient and compact lens system for coupling the laser light, and at the same time optimal heat dissipation from the laser diodes were of crucial importance in this project.
High Power Laser Module for Effect Lighting
For effect lighting, we have realized laser modules with high-power laser diodes with total light outputs of up to 100W. Red, blue and green lasers were collimated, coupled and homogenized to achieve the targeted beam profile.
Laser Module for Phosphor Conversion
To realize white light sources with superior luminance, we are developing modules with blue laser diodes that are focused on remote phosphor converter elements. Depending on the requirements, a few individual laser diodes or complete laser banks with many diodes are used. The laser beam collimation as well as the transverse and longitudinal beam shaping via lenses or mirror systems is a key aspect for achieving both powerful and compact systems.
