Fraunhofer Institute for Applied Solid State Physics IAFLast modified:
Researchers at Fraunhofer IAF have developed a laser-enhanced quantum sensor that combines high magnetic-field sensitivity with a large dynamic range. Using laser threshold magnetometry, they improved the ratio of sensitivity and dynamic range by a factor of up to 590 compared with state-of-the-art approaches. The breakthrough is enabled by the first demonstration of 100 percent optical contrast, combined with strong laser readout signals. The results, published in the journal Nature Communications, open up new prospects for medical diagnostics, navigation, and resource exploration.
