About This Webinar
Spectroscopy employs photonic tools to ascertain certain characteristics of matter. 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.

Its characteristically high photonic output powers and efficiency make it an excellent tool where matter must be accurately analyzed where the input power is limited. The DBR laser diode does this all while delivering a narrow linewidth (<500kHz) and stable polarization (300:1) providing excellent stability in its optical parameters while maintaining lock to its desired wavelength throughout its lifetime. Its deterministic and invariant wavelength tuning allows it to be fine-tuned, precisely to the application at hand.

About the presenter

Paul GolataAs Regional Sales Manager, Paul Golata, Ph.D., advances industry awareness of Photodigm’s Distributed Bragg Reflector (DBR) laser diode applications and attributes and ensures Photodigm customers are successful in utilizing their single-frequency semiconductors in high-technology solutions. He also provides design engineers with application and solutions support of the latest and most valuable technical information on DBR laser diodes which ensures Photodigm remains the leading supplier of DBR laser diodes in the world.

Golata is also known for his driven strategic leadership and tactical execution and prior to joining Photodigm he served in various manufacturing, marketing, and sales-related roles in photonics, electronics, and business verticals including at Hughes Aircraft Company, Melles Griot, Piper Jaffray, Balzers Optics, JDSU, Arrow Electronics, and Mouser Electronics. He holds a BSEET, an MBA, and a doctorate.

When Golata is not supporting DBR laser diode sales he is usually busy melting people's faces rocking out on his Les Paul or out for the day running in ultramarathon endurance events.
