Hybrid optical pumping of K and Rb atoms in a paraffin coated vapor cell

摘要

Dynamic hybrid optical pumping effects with a radio-frequency-field-drivennonlinear magneto-optical rotation (RF NMOR) scheme are studied in adual-species paraffin coated vapor cell. By pumping K atoms and probing$^{87}$Rb atoms, we achieve an intrinsic magnetic resonance linewidth of 3 Hzand the observed resonance is immune to power broadening and light-shifteffects. Such operation scheme shows favorable prospects for atomicmagnetometry applications.
