石蜡包被的Rb蒸气室中的慢光
Slow light in paraffin-coated Rb vapor cells
摘要：
我们目前的初步结果，从实验研究的慢光在反弛豫涂层Rb蒸汽细胞，并描述了这种细胞的建设和测试。包被的细胞壁允许的缓慢的基态退相干速率导致在宽基座顶部具有非常窄（<100 Hz）的透明峰的双结构的电磁诱导透明（EIT）光谱。这种双结构EIT允许光探测脉冲在两个时间尺度上以大大降低的群速度传播。我们讨论了正在进行的努力，以优化这种涂层细胞系统中的脉冲延迟。
英文摘要：
We present preliminary results from an experimental study of slow light in anti-relaxation-coated Rb vapor cells, and describe the construction and testing of such cells. The slow ground state decoherence rate allowed by coated cell walls leads to a dual-structured electromagnetically induced transparency (EIT) spectrum with a very narrow (<100 Hz) transparency peak on top of a broad pedestal. Such dual-structure EIT permits optical probe pulses to propagate with greatly reduced group velocity on two time scales. We discuss ongoing efforts to optimize the pulse delay in such coated cell systems.
