Laser-enhanced quantum sensing boosts sensitivity and dynamic range
Florian Schall, Lukas Lindner, Yves Rottstaedt +8
Magnetometers based on nitrogen-vacancy (NV) centers in diamond have emerged as the most important solid-state quantum sensors. However, ensembles are limited in optical contrast t…

Two-media laser threshold magnetometry: A magnetic-field-dependent laser threshold
Yves Rottstaedt, Lukas Lindner, Florian Schall +9
Nitrogen-vacancy (NV) centers in diamond are a promising platform for high-precision magnetometry. In contrast to the use of spontaneous emission in a number of NV-magnetometers, l…

High-contrast absorption magnetometry in the visible to near-infrared range with nitrogen-vacancy ensembles
Florian Schall, Felix A. Hahl, Lukas Lindner +6
Magnetometry with nitrogen-vacancy (NV) centers has so far been measured via emission of light from NV centers or via absorption at the singlet transition at 1042 nm. Here, we demo…
