等效噪声带宽小于1GHz的原子法拉第滤波器
Atomic Faraday filter with equivalent noise bandwidth less than 1 GHz
摘要：
利用铯蒸气中的D $_1$谱线，我们实现了一个等效噪声带宽小于1 GHz的原子带通光学滤波器。我们使用的ElecSus计算机程序，以找到最佳的实验参数，并发现，对于重要的数量的铯D $_1$线明显优于其他碱金属的D-线。在磁场为45.3高斯、温度为68.0 $\,^\circ$ C时，该滤波器的峰值透过率为77%，通带为310 MHz，等效噪声带宽为0.96 GHz。通过实验验证了模型的预测结果。实验和理论预测显示出很好的一致性。
英文摘要：
We demonstrate an atomic bandpass optical filter with an equivalent noise bandwidth less than 1 GHz using the D$_1$ line in a cesium vapor. We use the ElecSus computer program to find optimal experimental parameters, and find that for important quantities the cesium D$_1$ line clearly outperforms other alkali metals on either D-lines. The filter simultaneously achieves a peak transmission of 77%, a passband of 310 MHz and an equivalent noise bandwidth of 0.96 GHz, for a magnetic field of 45.3 gauss and a temperature of 68.0$\,^\circ$C. Experimentally, the prediction from the model is verified. The experiment and theoretical predictions show excellent agreement.
