Abstract
We investigate spectral response of synchronous coherent population trapping (SCPT) to demonstrate its suitability for remote magnetometry as well as for vector magnetic field measurements. Remote magnetometry is demonstrated using fluorescence measurements in a sodium cell. A magnetometer with real-time, single-shot vector magnetic measurement capability, is also demonstrated using the SCPT effect produced in a small rubidium cell and by combining our experimental apparatus with a feedback system.
