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…
Absorptive laser threshold magnetometry: combining visible diamond Raman lasers and nitrogen-vacancy centres
Sarath Raman Nair, Lachlan J. Rogers, David J. Spence +5
We propose a high-sensitivity magnetometry scheme based on a diamond Raman laser with visible pump absorption by an ensemble of coherently microwave driven negatively charged nitro…
Amplification by stimulated emission of nitrogen vacancy centres in a diamond-loaded fibre cavity
Sarath Raman Nair, Lachlan J. Rogers, Xavier Vidal +7
Laser-threshold magetometry using the negatively charged nitrogen-vacancy (NV-) centre in diamond as a gain medium has been proposed as a technique to dramatically enhance the sens…
The effects of thermal and correlated noise on magnons in a quantum ferromagnet
Jan Jeske, Ángel Rivas, Muhammad H. Ahmed +2
The dynamics and thermal equilibrium of spin waves (magnons) in a quantum ferromagnet as well as the macroscopic magnetisation are investigated. Thermal noise due to an interaction…
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…
Remote Nanodiamond Magnetometry
Yinlan Ruan, David A. Simpson, Jan Jeske +10
Optical fibres have transformed the way people interact with the world and now permeate many areas of science. Optical fibres are traditionally thought of as insensitive to magneti…
