我们报道了我们所知的第一个固体中的高分辨率布里渊增益谱。在熔融二氧化硅中观察到了对应于纵波(纵波)和横波(横波)的共振,具有良好的分辨率和高信噪比。测量了绝对增益系数、线宽和布里渊频移。与之前测量值的一致性很好。
We report what is to our knowledge the first high-resolution Brillouin gain spectrum in a solid. Resonances corresponding to longitudinal (compressional) and transverse (shear) acoustic waves in fused silica are observed with good resolution and a high signal-to-noise ratio. Absolute gain coefficients, linewidths, and Brillouin frequency shifts are measured. The agreement with previously measured values is good.
