Ultra-narrow parametric magnetic resonances in a miniature vapor cell Download: 991次
Abstract
Multi-photon parametric magnetic resonance in a miniature vapor cell is demonstrated. Much more multi-photon magnetic resonance can be observed when the radio frequency field becomes stronger. The linewidth of the n photons magnetic resonance equals that of the first-order resonance divided by n , which means that the uncertainty of the magnetic sublevel is reduced by the factor n . The signal-to-noise ratio can be improved when the low-frequency multi-photon resonance takes place, which finds a possible application in precision magnetic field measurement.
