Optoelectronics

At Fraunhofer IAF, we carry out research on innovations in both optoelectronic components and systems.

 

We develop infrared semiconductor lasers, laser systems based on them as well as LED modules, infrared and UV detectors specifically for your field of application.

In the field of semiconductor lasers, we focus on the technologies of optically pumped semiconductor disk lasers and quantum cascade lasers (QCL). The semiconductor lasers cover the wavelength range from 2 – 11 µm.

Our detector technology for applications in Stirling-cooled, high-resolution cameras and in industrial measurement technology for the mid- and long-wave infrared is unique worldwide. It enables the production of spatially high-resolution, high-performance thermal imaging cameras, which either operate in the classic monospectral mode or have the capability of color vision in the infrared.

Our semiconductor lasers and detectors can be used for a variety of applications: from quality control of food and pharmaceuticals to monitoring industrial processes and detection of explosives.
