摘要： A magnetometer for use with a sample including an atomic vapor includes a cell containing the sample such as a multipass cell including a first mirror element and a second mirror element configured so that an incoming light beam injected into the container will reflect multiple times between the first mirror element and the second mirror element. A polarized pump light source is configured to transmit pump light through the cell and pump the sample. A polarized probe light source configured to transmit probe light through the cell and probe the sample. A detector configured to detect a polarization angle or intensity of the probe light transmitted through the sample. A processor may be configured to calculate a precession frequency of the sample based on a first probe light pulse and a frequency correction based on a second probe light pulse.
