提出了一种利用光频梳实现宽带平坦布里渊增益和低失真慢光的新方法，利用光频梳产生技术获得了由20条离散谱线组成的泵浦光，并获得了带宽为200 MHz的平坦SBS增益。对于持续时间为5.44 ns的脉冲，我们实现了2.46的较大相对脉冲延迟，同时将展宽因子抑制到小于1.19。
We present a novel method for realizing a slow light with a broadband flat Brillouin gain and low distortion by using an optical frequency comb. We obtained a pump light consisting of 20 discrete line spectra using an optical frequency comb generation technique and a flat SBS gain with a 200 MHz bandwidth. We have realized a large relative pulse delay of 2.46 while suppressing the broadening factor to less than 1.19 for a pulse with a duration of 5.44 ns.
