Characterizing the nitrogen-vacancy center singlet transition and its phonon sideband for absorption-based room-temperature magnetometry
Tobias Probst, Florian Schall, Sebastian Heuft +9
Magnetometry with nitrogen-vacancy (NV) centers in diamond has shown great promise in recent years. In particular, absorption-based magnetometry techniques, employing a cavity to e…
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…
Diamond quantum magnetometer with dc sensitivity of < 10 pT Hz toward measurement of biomagnetic field
N. Sekiguchi, M. Fushimi, A. Yoshimura +10
We present a sensitive diamond quantum sensor with a magnetic field sensitivity of in a near-dc frequency range of 5 to 100~Hz. This sensor is b…
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…
Magnetic field-induced enhancement of the nitrogen-vacancy fluorescence quantum yield
M. Capelli, P. Reineck, D. W. M. Lau +6
The nitrogen-vacancy (NV) centre in diamond is a unique optical defect that is used in many applications today and methods to enhance its fluorescence brightness are highly sought…
