Title: Sensitivity Comparison of Mx and Frequency Modulated Bell-Bloom Cs Magnetometers in a Micro-Fabricated Cell
Published: February 01, 2010
Abstract: We compare the sensitivity performance of two optically pumped atomic magnetometers based on the Mx and frequency-modulated Bell-Bloom configurations. The Cs magnetometers are implemented using a millimeter-scale microfabricated vapor cell in a configuration in which a single laser beam serves as both pump and probe. It is found that the single-beam Bell-Bloom magnetometer yields sensitivities similar to those of the Mx magnetometer when operated under the same optimized conditions. The Bell-Bloom approach offers several attractive features over the Mx approach for chip-scale magnetometer-instrumentation.
