Abstract

We use the dressed-atom formalism to calculate the frequency shift in a hydrogen maser induced by applied radiation near the Zeeman frequency, and find excellent agreement with a previous calculation made in the bare-atom basis. The maser oscillates on the ΔF=1, ΔmF=0 hyperfine transition, while the applied field is swept through the F=1, ΔmF=±1 Zeeman resonance. We determine the effect of the applied field on the Zeeman levels using the dressed-atom picture, and then calculate the maser frequency shift by coupling the dressed states to the microwave cavity. Qualitatively, the dressed-atom analysis gives a simpler physical interpretation of this double-resonance process, which has applications in precision hydrogen Zeeman spectroscopy, e.g., in fundamental symmetry tests.
