About Us

Advanced laser systems for next-generation technologies

Bergfeld Lasertech GmbH develops advanced laser processes and laser systems for thin films, functional surfaces, and high-precision applications in research, development, and pilot production.

Based in Aachen, Germany, we work at the intersection of scientific innovation and practical engineering. Our core focus lies in laser-based solutions for photovoltaics, battery technologies, fuel cells, hydrogen-related applications, and printed or organic electronics.

Our customers include research institutes, start-ups, and established industrial companies looking for reliable, application-specific laser technology. We design and manufacture systems that combine precision, flexibility, and process reliability — from highly specialized laboratory environments to pilot-scale production setups.

One of our particular strengths is the development of laser systems for glove box integration and other controlled process environments. In addition, we support our customers with tailored concepts for process integration, laser processing modules, and laser safety documentation and certification.

Beyond machine engineering, Bergfeld Lasertech stands for deep process expertise. With our multi-wavelength laser systems, several processing steps can often be combined within a single setup, enabling efficient, selective, and scalable material processing for demanding technological applications.

With administration and development in Aachen and production in Herzogenrath-Kohlscheid, we combine scientific know-how, engineering excellence, and close collaboration with our customers to create laser solutions for the technologies of tomorrow.
