The research project PrOpSys (production technology of optical systems for high-power diode lasers) has demonstrated a fully automated assembly and adjustment of a high-power diode laser. Created to target the development of technical bases for mass-production-suited designs and the associated fully automatic manufacturing technology for micro-optical systems and high-power diode lasers, the project is funded by the BMBF (German federal ministry of education and research) and will continue to utilize the research of companies and institutes.
