Coherent stimulated Raman emission from a microcavity-excited optical resonator.
We report the observation of coherent emission from a planar Fabry-Perot resonator driven by a single, coherently emitting microcavity. The microcavity, either a liquid microdroplet or microcylinder, emits coherent stimulated Raman scattering when irradiated by an intense pump laser; the Raman light, in turn, couples to modes of the resonator. The spatiotemporal characteristics of resonator emission are strongly influenced by the microcavity source within; notably, a significant excess time delay in the emission of stimulated Raman scattering (i.e., compared with that of the microcavity in free space) accompanies the appearance of a sharp resonator spatial interference pattern. This and other noteworthy features are described, and a qualitative discussion of their significance is given.
