Raman lasing in optofluidic microbubble resonator

Raman lasing has been realized in different kinds of whispering gallery mode microresonators because of its high quality factors and relatively small mode volumes. The non-linear coefficient of carbon disulfide is much larger than that of silicon dioxide. In this paper, we fabricate a high quality factor silica microbubble resonator. In addition, we report on the realization of Raman lasing in an empty silica microbubble resonator. Moreover, Raman lasing in carbon disulfide filled optofluidic microbubble resonator at pump wavelengths of 950 nm is also implemented.
