Infrared lasers for spectroscopy

Quantum cascade lasers (QCLs) combine a broad spectral tuning range of more than hundreds of wavenumbers with high spectral brightness. The infrared application laboratory at Fraunhofer IAF aims to bridge the gap between laser source and measurement system development at Fraunhofer IAF and customers.
