- W3157824464 abstract "Abstract 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 nitrogen-vacancy centres (NV − ) in the same diamond crystal. The NV − centres’ absorption and emission are spin-dependent. We show how the varying absorption of the NV − centres changes the Raman laser output. A shift in the diamond Raman laser threshold and output occurs with the external magnetic field and microwave driving. We develop a theoretical framework with steady-state solutions to describe the effects of coherently driven NV − centres including the charge state switching between NV − and its neutral charge state NV 0 in a diamond Raman laser. We discuss that such a laser working at the threshold can be employed for magnetic field sensing. In contrast to previous studies on NV − magnetometry with visible laser absorption, the laser threshold magnetometry method is expected to have low technical noise, due to low background light in the measurement signal. For magnetic-field sensing, we project a shot-noise limited DC sensitivity of a few pT <?CDATA $/sqrt{mathrm{H}mathrm{z}}$?> <mml:math xmlns:mml=http://www.w3.org/1998/Math/MathML display=inline overflow=scroll> <mml:mo>/</mml:mo> <mml:msqrt> <mml:mrow> <mml:mi mathvariant=normal>H</mml:mi> <mml:mi mathvariant=normal>z</mml:mi> </mml:mrow> </mml:msqrt> </mml:math> in a well-calibrated cavity with realistic parameters. This sensor employs the broad visible absorption of NV − centres and unlike previous laser threshold magnetometry proposals it does not rely on active NV − centre lasing or an infrared laser medium at the specific wavelength of the NV − centre’s infrared absorption line." @default.
