Abstract
We fabricate a tapered fiber coupler, position it near an ultrahigh- 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 . Both pump and Raman laser modes overlap with the liquid phase instead of just residually extending to the fluid.
