摘要
报道了我们在85Rb热原子系统中利用远离共振的Raman动力学过程实现相干光信号存储与释放的实验研究。铷原子室采用μ-metal包裹消除环境磁场的影响,在双光子共振和单光子远失谐的条件下,我们测量了存储效率随存储时间及单光子失谐量的变化关系,得到的最高存储效率为23.5%,寿命约为3.4μs。
By using off-resonant Raman dynamic, we investigate the storage and release of light in atomic rubidium vapor, u-metal shielding wrap the Rubidium cell to eliminate the influence of environmental magnetic field, under the condition of two-photon resonance and single photon detuning, We measured the changes in the relationship between storage efficiency with storage time and single-photon detuning. In our experiment, the highest storage efficiency of the stored signal is 23.5 %, and its life is about 3.4 μs.
