LaserSenseI

Development of an InGaAs-based KISA sensor for near-infrared applications

The LaserSenseI project is advancing the development of an intelligent, compact sensor designed to characterize lasers in the near-infrared (NIR) range. Measuring devices in this spectral region are currently associated with high costs for users, creating a significant barrier to adoption. Building on Coher Sense’s proven KISA sensor platform, LaserSenseI will deliver a next-generation solution tailored to the unique demands of the NIR. The new sensor will fill critical gaps in existing technology, enabling cost-effective and precise laser characterization for applications in laser communication, industrial process and structural monitoring, and advanced scientific instrumentation.

LaserSenseI is funded by the State Economic Program 2021-2027 with funds from the European Regional Development Fund.

RaInIso-DS

Polarized Raman interferometer for isomer discrimination

(Completed)
As part of the study, a prototype setup based on a polarization interferometer was developed and successfully tested. Simulations and measurements confirmed high resolution and demonstrated the ability to detect Raman signals. Optical tests with calibration sources verified both the interferometric detector and the integrated Raman module, while design optimizations improved signal quality by several orders of magnitude. Final measurements with standard chemicals confirmed reliable system performance. Overall, the project demonstrated the feasibility and strong application potential of a compact Raman system for chemical analysis.

This project was supported by the Federal Ministry of Economic Affairs and Climate Action (BMWK) on the basis of a decision by the German Bundestag.
