In a recent article [Opt. Express 17, 17317 (2009)] Kovalev et al. claimed that SBS-induced group index is always negligibly small, regardless of the intensity and bandwidth of pump radiation. In this comment, we show that their conclusions are not valid in any practical conditions in which SBS-based slow light experiments are carried out.
在最近的一篇文章[《光学快报》17, 17317 (2009)]中，科瓦列夫等人声称，受激布里渊散射（SBS）诱导的群折射率总是小到可以忽略不计，与泵浦辐射的强度和带宽无关。在这篇评论中，我们表明他们的结论在进行基于SBS的慢光实验的任何实际条件下都是无效的。
