Photonics Media 2023 Spectroscopy Conference

Photonics Media asked Paul Golata, our Regional Sales Manager, to share his insights on “What’s the matter? Distributed Bragg Reflector (DBR) Laser Diodes Enable the Study of Matter” as a part of the Photonics Spectra 2023 Spectroscopy Conference.

In this video, Paul discusses how the ever-increasing push towards studying matter within application spaces demanding low size, weight, power, and cost (SWaP-C) requires an appropriate photonic tool. DBR laser diodes bring a unique ability to break boundaries in Raman, biomedical, food inspection, art conservation/cultural heritage, and environmental situations where matter is being analyzed. Combining excellent SWaP-C characteristics, the DBR laser diodes’ inherent monolithic structure ensures ruggedness and scalability in critical and high-volume applications.
