Visible nonlinear stimulated scatterings generated in a carbon disulfide filled microbubble cavity

In recent years, multicolor lasers have shown high potential for applications in many fields, such as white light source generation, biosensor or bioimaging, and optical communication, etc. Here, we use an optofluidic microbubble resonator (OFMBR) filled with a highly nonlinear liquid to obtain multicolor stimulated scatterings. By filling OFMBR with carbon disulfide and pumping it with nanosecond pulsed laser, a broadband visible supercontinuum spanning from 532 nm to 630 nm is generated due to the stimulated Raman scattering and stimulated Raman-Kerr scattering. This study opens the way towards potential application of multicolor or white light generation using optical nonlinear liquids.
