大原子相干增强磁光效应
Enhancement of Magneto-Optic Effects via Large Atomic Coherence
摘要:
我们利用大原子相干性的产生,将共振非线性磁光效应提高了几个数量级,从而消除了功率展宽,提高了基波信噪比。在Rb原子的稠密蒸气中进行了原理验证实验。详细的数值计算与实验结果吻合良好。应用,如光学磁强计或违反宇称和时间反演对称性的搜索是可行的。
英文摘要:
We utilize the generation of large atomic coherence to enhance the resonant nonlinear magneto-optic effect by several orders of magnitude, thereby eliminating power broadening and improving the fundamental signal-to-noise ratio. A proof-of-principle experiment is carried out in a dense vapor of Rb atoms. Detailed numerical calculations are in good agreement with the experimental results. Applications such as optical magnetometry or the search for violations of parity and time reversal symmetry are feasible.
