We demonstrate stimulated supercontinuum-radiation of carbon disulfide(CS_2) influenced by biological molecules all-trans-β-carotene in liquid core optical fibre(LCOF).By virtue of the broad fluorescence characteristics and large third-order optical nonlinearities of all-trans-β-carotene,the high-order Stokes lines of stimulated Raman scattering (SRS) and the multi-order Stokes lines of stimulated Brillouin scattering(SBS) excitated by SRS are observed at low input-laser energies.The results indicate that the fluorescence not only enhances the SRS,but also the SBS.These Stokes lines generate the SRS-SBS supercontinuum radiation(RBSR).A flat-amplitude bandwidth of ffO nm from 515 nm to 625 nm is observed when a frequency-doubled Nd:YAG laser at 532 nm with an energy of 0.86 mJ is used. This result is expected to be useful for the multi-wavelength fibre laser.
