Abstract: (3016 Views)
Optically pumped atomic magnetometers are one the most sensitive sensors introduced for the measurement of the extremely weak magnetic fields. The sensitivity of these magnetometers can be improved by using the optimum operating conditions. In this paper, the influence of laser beam power, cell temperature and rf field strength on the magnetometer sensitivity, using resonance absorption and dispersion of the light beam passing through a rubidium vapor, has been simulated. Our theoretical predictions indicate that a great reduction in the sensitivity can be observed under the best selection of affecting parameters.
