Abstract
One embodiment includes a nuclear magnetic resonance (NMR) sensor system. The system includes a pump laser configured to generate an optical pump beam at a first wavelength and a probe laser configured to generate an optical probe beam at a second wavelength that is different from the first wavelength. The system also includes beam optics configured to direct the pump laser and the probe laser along orthogonal axes through a sensor cell comprising an alkali metal vapor. The system further includes detection optics that include a photodetector assembly configured to measure at least one characteristic associated with the optical probe beam leaving the sensor cell for measurement of a polarization vector of the alkali metal vapor. The detection optics can include at least one filter configured to filter light having the first wavelength and to pass light having the second wavelength to the photodetector assembly.
