Fluorescence seeding by dissolving a fluorescent dye in a liquid droplet enhances the stimulated Raman scattering of a weaker-gain Raman mode. With the dye fluorescence at the Stokes wavelength of the weaker-gain Raman mode, the weaker-gain Raman mode can now build up from the much stronger fluorescence instead of from the weaker spontaneous Raman scattering. With fluorescence seeding, the weaker-gain C-C-O Raman mode of ethanol can be observed at a much lower input-laser intensity and can be more intense than the stronger-gain C-H Raman mode.
通过将荧光染料溶解在液滴中来进行荧光种子注入，可增强较弱增益拉曼模式的受激拉曼散射。由于染料荧光处于较弱增益拉曼模式的斯托克斯波长，较弱增益拉曼模式现在可以从强得多的荧光而不是较弱的自发拉曼散射中积累起来。通过荧光种子注入，乙醇较弱增益的C-C-O拉曼模式在低得多的输入激光强度下就能被观测到，并且其强度可能比增益较强的C-H拉曼模式还要高。
