“…We can see that two peaks are shown. One is at 532 nm consisting There is no anti-Stokes component in it, which indicates that SRS occurs [13]. To distinguish spectral detail in the peak at 532 nm, F-P etalon with the free spectral range of 10 GHz is used.…”

“…Nevertheless, the spectral characteristics of the backscattered beam, the SBS reflectivity, the pulse-shape (PS) fidelity, and phase conjugation (PC) fidelity in LCOF with a short pump pulse were not observed experimentally. In addition, the thresholds for stimulated Raman scattering (SRS) in LCOFs also decrease dramatically for a laser with the pulse width of the order of several ns [13]. The relationship between SBS and backward SRS (BSRS) was not clearly understood.…”

The characteristics of stimulated Brillouin scattering (SBS) in a liquid-core optical fiber (LCOF) contained CS 2 with 10 ns pulses at 532 nm wavelength are investigated experimentally. The threshold, reflectivity, pulse-shape (PS) fidelity, and phase-conjugation (PC) fidelity of LCOFs with different core diameters and lengths are measured. Threshold energy is as low as 2.5 µJ, and the SBS reflectivity, the PS fidelity, and PC fidelity exceed simultaneously 90 % when the input energy is over 20 times threshold.

“…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]. But the intermolecular Fermi resonance to enhance the SRS has not been researched as far as we know.…”

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.

We demonstrated the growth profile of stimulated Raman anti-Stokes scattering (SRS) of carbon disulfide (CS 2 ) influenced by fluorescence seeding of all-trans-β-carotene and rhodamine-B (RhB) in liquid-core optical fiber (LCOF). The pump energy which was needed to build up the first-order anti-Stokes radiation of CS 2 solutions with the fluorescence seeding was lower than that of CS 2 solutions without fluorescence seeding because of the fluorescence enhancement effect on the intensity of the first-order Stokes radiation. The first-order anti-Stokes radiation of the RhB solution (10 −8 M) was built up at a lower pump energy than that of the all-trans-β-carotene solution (10 −6 M), and the intensity of the first-order anti-Stokes radiation of the RhB solution was higher than that of the all-trans-β-carotene solution. Simultaneously, the coupled wave differential equations were obtained by the theoretical derivation, and the growth profile of the first-order anti-Stokes radiation was theoretically calculated with and without the fluorescence seeding by these equations.
