我们报道了使用全原子频率梳状存储方案的光的相干和多时间模式存储。该方案包括利用强单频转移脉冲将Pr3+：Y2SiO5中的光学原子激发转移到超精细水平的自旋波。使用该方案，总共存储了五个时间模式，并根据需要从存储器中调用。使用时间绑定干涉测量来表征存储和检索的相干性，从而与存储时间无关地产生高于80%的可见度。这种相干和多模的自旋波存储器有望成为光的量子存储器。
We report on the coherent and multi-temporal mode storage of light using the full atomic frequency comb memory scheme. The scheme involves the transfer of optical atomic excitations in Pr3+:Y2SiO5 to spin waves in hyperfine levels using strong single-frequency transfer pulses. Using this scheme, a total of five temporal modes are stored and recalled on-demand from the memory. The coherence of the storage and retrieval is characterized using a time-bin interference measurement resulting in visibilities higher than 80%, independent of the storage time. This coherent and multimode spin-wave memory is promising as a quantum memory for light.
