摘要
我们在光学参量放大器中产生了波长为 795 nm、压缩度为 1.86-dB 的 600-ns 压缩真空脉冲，并利用电磁诱导透明技术将其存储在铷蒸气室中长达 1 us。使用时域零差断层扫描技术对恢复后的脉冲进行分析，显示出高达 0.21+-0.04 dB 的压缩度。我们确定了导致压缩度退化的因素，并研究了存储间隔期间原子相干的相位演化。

评论
To appear in PRL. Changes to version 3: we present a larger data set featuring somewhat less squeezing, but also better statistics and a lower margin of error. Some additional revisions are made in response to the referees' comments
