摘要:

固定光脉冲(SLP),即,没有运动的光脉冲是通过用两个反向传播的耦合场检索存储的探测脉冲而形成的。我们发现,在冷原子介质中存在不可忽略的混杂拉曼激发,阻止了SLP的形成。我们在实验上证明了一种方法,以抑制这些拉曼激发,实现激光冷却原子中的SLP。我们的工作为冷原子和静止原子中的SLP研究开辟了道路,并为微光非线性光学提供了一条新的途径。

英文摘要:

Stationary light pulses (SLPs), i.e., light pulses without motion, are formed via the retrieval of stored probe pulses with two counter-propagating coupling fields. We show that there exist non-negligible hybrid Raman excitations in media of cold atoms that prohibit the SLP formation. We experimentally demonstrate a method to suppress these Raman excitations and realize SLPs in laser-cooled atoms. Our work opens the way to SLP studies in cold as well as in stationary atoms and provides a new avenue to low-light-level nonlinear optics.
