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…

Magnetic-Field-Dependent Stimulated Emission from Nitrogen-Vacancy Centres in Diamond
F. Hahl, L. Lindner, X. Vidal +9
Negatively charged nitrogen-vacancy centres in diamond are promising quantum magnetic field sensors. Laser threshold magnetometry has been a theoretical approach for the improvemen…
