BriSCL: Brilliant SemiConductor LaserModules

A cooperation under the roof of Eurostars with the following partners

Project Goals

BriSCL uses novel beam combining, optical resonators, diode laser designs and R&D cutting-edge technology to
enable brighter diode laser modules for the world’s largest laser market: material processing. The technology is
proven, patented, and used in BriSCL to enable further innovation and power scaling. BriSCL will directly produce
> 8x brighter direct diode laser platforms and 4x brighter fibre laser pumps without compromising cost and
efficiency (>40%).


Monocrom will do the system integration on the level of laser bars. Freespace and fiber coupled laser engines up to a few kW will result.

Project BriSCL exploits highly efficient diode ASLOC laser designs and buried-regrown-implant-structure (BRIS) device technology from the Ferdinand Braun Institut gGmbH, Berlin, Germany, to enable higher brightness industrial lasers at wavelengths around 915 nm, with a special focus on devices that are consistent with high yield and high performance assembly.

Raab-Photonik is in charge of developing, simulating and optimizing the concepts of "Rectified Polarization Coupling" (RPC) for power scaling power density of diode lasers without enlarging the BPP.

Also Raab-Photonik will follow up on fundamental concepts of external resonators for improving the divergence and power density of single emitters.

Brilliance FAB Berlin GmbH (BFB) mounts both single emitters and bars of the newly developed semiconductor structures. They will integrate systems on the basis of single emitters.

JENOPTIK Optical Systems GmbH (Berlin) is associated partner of the project and evaluates the newly developed laser structures for future mass production.
