提出了一种基于受激布里渊散射(SBS)的超高分辨率光谱分析方法。受受激布里渊散射固有带宽的限制，传统光谱仪的分辨率受到限制。我们通过减小自然的SBS增益带宽来提高分辨率。通过叠加自然增益和两个损耗，我们能够将光谱仪的分辨率从20 MHz提高到8 MHz。我们将在第一个概念验证实验中确认这一点。
We present a method for ultrahigh-resolution optical spectroscopy based on stimulated Brillouin scattering (SBS). The resolution of conventional spectrometers is limited by the natural bandwidth of the SBS. We enhance the resolution by a reduction of the natural SBS gain bandwidth. By a superposition of the natural gain with two losses, we were able to increase the spectrometer resolution from 20 to 8 MHz. We will confirm this in a first proof of concept experiment.
