✦ Synopsis
We have observed that in a binary mixture microdroplet, stimulated Raman scattering (SRS) from the highest-gain mode of the majority species pumps the SRS from the minority species and a weaker-gain mode of the majority species more efficiently than does the input laser. The spatial overlap between the pumping field and the SRS field is an important factor in determining the pumping efficiency. We have numerically studied the effect of spatial overlap. Qualitative discussions are made of the effects of some other factors, such as concentration and Raman gain of the majority species.
