Abstract
We fabricate a tapered fiber coupler, position it near an ultrahigh-Q resonator made from a microdroplet, and experimentally measure stimulated Raman emission. We then calculate the molecular vibrational mode associated with each of the Raman lines and present it in a movie. Our Raman laser lines show themselves at a threshold of 160 μW input power, the cold-cavity quality factor is 250 million, and mode volume is 23 μm3. Both pump and Raman laser modes overlap with the liquid phase instead of just residually extending to the fluid.
