论文摘要
我们在这里提出了一个新的参数共振磁力计方案，该方案基于椭圆极化的泵送光和沿两个光学泵送方向应用的两个射频场。在最佳椭圆时和射频场振幅下，磁场的三个组件以各向同性灵敏度测量。与通常的基于对齐的参数谐振磁力计相比，灵敏度被磁场的两个成分的因子2降解，但第三个因子11改进了因子11。对于地球物理和生物医学成像，这种新的磁力计配置可能特别有趣。
We present here a new parametric resonance magnetometer scheme based on elliptically polarized pumping light and two radio-frequency fields applied along the two optical pumping directions. At optimum ellipticity and radio-frequency fields amplitudes the three components of the magnetic field are measured with an isotropic sensitivity. Compared to the usual alignment-based parametric resonance magnetometers, the sensitivity is degraded by a factor 2 for two components of the magnetic field but improved by a factor 11 for the third one. This new magnetometer configuration could be particularly interesting for geophysics and biomedical imaging.
