One example embodiment includes an atomic sensor system. A probe laser generates a probe beam. A first portion of the probe beam is provided through a sensor cell comprising a first alkali vapor to calculate a measurable parameter of the system based on a first detection beam corresponding to the first portion of the probe beam exiting the sensor cell. A second portion of the probe beam can be provided through a stabilization cell that comprises a second vapor. A detection system can be configured to stabilize the frequency of the probe beam in a manner that is on-resonance with respect to an optical transition wavelength of the second alkali vapor and off-resonance with respect to an optical transition wavelength of the first alkali vapor based on a second detection beam corresponding to the second portion of the probe beam exiting the stabilization cell.
