Description
One of the most sensitive methods for magnetic field measurement employs quantum phenomena at atomic level. We use the Doppler-free saturated absorption spectroscopy to reveal the hyperfine levels of the rubidium atoms which obscured by the thermal broadening, we able to observe the splitting of energy levels due to an external magnetic field. Furthermore, effect of polarization of the light beam is changing the rubidium spectrum as a consequence to the optical pumping process. The measured of the energy separated subsistence an external magnetic field use toward to atomic magnetometry or analysis various theories.
