“…However, the relevant application and research are limited because of the high SRS threshold and low SRS intensity. In order to lower the threshold of SRS and enhance the intensity of SRS, some methods are applied, such as fluorescent dyes to enhance the SRS [7], micrometer-sized droplets to enhance the SRS [8,9], liquid-core optical fibers (LCOFs) to enhance the SRS [10], intramolecular Fermi resonance to enhance the SRS [11] and so on. The fluorescent dye enhancement to SRS in a LCOF has been investigated by our team in the last few years [12,13].…”

We demonstrate the stimulated Raman scattering (SRS) of a binary solution of toluene and m-xylene at different volume concentrations in liquid-core optical fiber (LCOF). The results show that SRS of three vibration modes of 1002 cm −1 , 2920 cm −1 and 3058 cm −1 bands are simultaneously generated at some volume concentrations. The 2920 cm −1 band and the 3058 cm −1 band are generated at one time, the SRS thresholds of the first-order Stokes of the 2920 cm −1 and 3058 cm −1 bands are lower compared with the second-order Stokes threshold of the 1002 cm −1 band and the main peak of the 2920 cm −1 and 3058 cm −1 bands changes from the 2920 cm −1 band to the 3058 cm −1 band as the volume concentrations are changed. We assume that these phenomena are attributed to the intermolecular Fermi resonance. Raman scattering cross section (RSCS) theory is used to explain this assumption.
