摘要
An optical magnetometer comprising: a response frequency measurement unit comprising a vapor cell, a pulsed-mode pump laser and a probe laser; and a computing unit configured to compute a magnetic field change based on a difference between at least two temporally-distinct response frequency values received from the frequency measurement unit. Optionally, the response frequency measurement unit is magnetically non-shielded.
