Infrared laser threshold magnetometry using diamond NV centers

Résumé

We theoretically study a hybrid laser magnetometer cavity combining a semiconductor medium to obtain the optical gain and a diamond etalon containing nitrogen vacancy (NV) colored centers as magnetic field probe. This architecture avoids the issue of excited state absorption by the NV centers and could end up with equivalent magnetic field noise of 1pT/Hz^0.5. Moreover, unlike usual IR NV center magnetometry this technique does not require the use of an external frequency stabilized probe laser tuned to the IR transition. This simplification is of interest for targeting practical applications.
