We develop diode lasers that serve the special requirements of light sources in the field of sensor technology and analytics. They are specifically tailored to applications in laser spectroscopy. These include tunable light sources for absorption spectroscopy and dual-wavelength diode lasers for applications in Raman and Shifted Excitation Raman Difference Spectroscopy (SERDS) or THz spectroscopy. The work in the Laser Sensors Lab covers the entire value chain from the diode laser to the light source to the measurement system.
For the qualification of the developments directly in the application, various Raman measuring stations and a Raman microscope are available. Jointly with our Prototype Engineering Lab we also realize portable Raman measuring sysstems for on-site measurements. This interaction allows conclusions and thus even more targeted further developments of the lasers and systems regarding the applications and for our partners.
In addition, in the Laser Modules Lab we develop customized miniaturized light sources for both STED and time-resolved fluorescence spectroscopy as well as modules for the mid-IR range for quantum OCT or spectral quantum light microscopy.
Based on our dual-wavelength diode lasers, our Prototype Engineering Lab has developed a turnkey control system. It allows in situ measurements of Raman signals even outside of the laboratory. The system unites laser chip technology, optimized cooling and a flexibele control unit in a compact housing. Combined with a Raman spectrometer and FBH’s measurement software, Raman signals can be measured based on the SERDS method.
