    "abstract": "We observe quantum beats with periodic revivals due to non-linear spacing of\nZeeman levels in the ground state of potassium atoms and demonstrate their\nsynchronous optical pumping by double modulation of the pumping light at the\nLarmor frequency and the revival frequency. We show that synchronous pumping\nincreases the degree of spin polarization by a factor of 4. As a practical\nexample, we explore the application of this double-modulation technique to\natomic magnetometers operating in the geomagnetic field range and find that it\ncan increase the sensitivity and reduce magnetic field orientation-dependent\nmeasurement errors endemic to alkali-metal magnetometers.",
