Diamond-based quantum sensors

We develop diamond-based quantum sensors that can detect magnetic and electric fields with a spatial resolution of just a few nanometers down to individual electron and nuclear spins. Due to its outstanding physical properties, diamond quantum sensors work at room temperature - ideal for industrial applications.

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.
