A novel nonlinear optical effect: Stimulated Raman–Kerr scattering in a benzene liquid-core fiber

Abstract

By using a long interaction length (250 cm) provided by a liquid (benzene)-core multimode hollow fiber, we have observed a novel superbroadening stimulated scattering added to the first- and second-order Stokes stimulated Raman scattering lines of liquid benzene. To explain this new effect, a photon-scattering model of Raman-induced optical Kerr effect, named as Raman–Kerr scattering, is proposed.
