UV-B LED module triggering the biosynthesis of secondary metabolites in plants
Ferdinand-Braun-Institut (FBH) develops LEDs in the UV-B and UV-C spectral range. Applications include UV curing, phototherapy, plant growth lighting (image: module designed to increase the content of health-promoting secondary plant metabolites), and medical diagnostics. FBH covers the full value chain inhouse, from the semiconductor material to device fabrication. UV LEDs are available as fully processed wafers, bare chips or mounted on submounts and TO headers, and ready-to-use modules.
Customized diode lasers improving Raman spectroscopy in real-world applications
The Ferdinand-Braun-Institut (FBH) develops customized diode lasers and systems for Shifted Excitation Raman Difference Spectroscopy. Developments include monolithic dual-wavelength diode lasers providing two stabilized wavelengths together with a small spectral linewidth. The devices allow fast alternating operation with an adjustable spectral distance. As a result, Raman signals can be extracted rapidly from disturbing backgrounds, thus improving Raman spectroscopy in real-world applications.
High duty cycle, highly efficient fiber coupled 940-nm pump modules for high-energy class solid-state lasers
FBH develops diode lasers with the largest optical intensities and efficiency, e.g. as pump modules for high-energy-class laser systems. The corresponding Yb-doped solid-state amplifiers must operate at high repetition rates (≥ 100 Hz) with long pulses (0.5…2 ms). Application-ready pump modules, shown here, address these needs, leveraging innovative wide-aperture single emitters in passively-side-cooled stacks to deliver 6 kW output power in a multi-mode fiber (1.9 mm NA 0.22).
The Ferdinand-Braun-Institut (FBH) has developed a very compact laser module with emis-sion at 633 nm. The semiconductor laser module, sized only 76x54x15 mm³, uses a novel butterfly-type housing and aims at replacing bulky HeNe lasers. It offers a flexible platform for the integration of a...| » Further reading
