The T-Cognition terahertz spectrometer was recognized in the category of »Defense and Security”, and the C-Wave optical parametric oscillator convinced the jury in the »Scientific Lasers« category. Both systems were developed jointly by Fraunhofer IPM and Hübner GmbH & Co. KG. The Prism Awards are one of the most important international scientific prizes for modern photonics applications.

 »This dual success is an especially impressive example of productive collaboration between research and industry,« says Karsten Buse, head of Fraunhofer IPM, »The T-Cognition system shows that, while still quite young, terahertz technology is now ripe for industrial application. And with the C-Wave tunable laser light source, the partners succeeded in creating a true world first in field of laser technology!«

T-Cognition: Terahertz spectrometer for monitoring postal mail

The T-Cognition terahertz spectrometer is an automated system for spotting hidden drugs and explosives in letters and small packages. Within a few seconds, T-Cognition identifies concealed substances using their characteristic spectroscopic fingerprint. This security check is done without the need to open the letters or parcels, thus respecting the privacy of mail. In this way, T-Cognition enhances security in mailrooms, penal institutions, customs stations or exposed facilities, such as embassies.

C-Wave: Continuous laser light throughout the visible spectral range

Optical parametric oscillators (OPOs) are ideal light sources for spectroscopy. C-Wave is the first available OPO that emits continuous laser light over the entire visible spectral range. This has many practical advantages: For one thing, it does away with the need to change laser media or components. In contrast to dye lasers, the solid-state C-Wave requires no exchange of toxic dyes. The one-year cooperation between the Laboratory of Optical Systems at Freiburg University, Fraunhofer IPM and Hübner GmbH & Co. KG has led to an award-winning commercial product.

The Prism Awards are one of the most important international scientific prizes for modern photonics applications. Since 2008, they have been awarded by SPIE, an international society for optics and photonics. The winners were announced on February 6 at the world’s most important photonics trade show, Photonics West, in California.
