In this paper, based on the ideal stimulated Raman coupling equation, the dynamic output state is investigated. Considering the gain and loss of stimulated Raman scattering in the actual situation, the ideal stimulated Raman coupling equation is modified. Furthermore, the influence of optical loss on the nonlinear effect in the stimulated Raman scattering system has been analyzed. The results show that, considering the gain and loss of the system, the dynamic output of the stimulated Raman coupling equation presents stable periodic oscillation and random oscillation.

Stimulated Raman

We show through experiments of stimulated Raman scattering how solid hydrogen (parahydrogen) can open new perspectives on nonlinear optics. Two phenomena are described: One is the self-induced phase matching in parametric anti-Stokes stimulated Raman scattering (SRS) in which the phase matching is self-organized automatically without the stringent restriction of refractive-index dispersion of the medium, and the other is the extremely slow coherence decay behavior for the Raman transition that may result in the Raman width of 80 kHz full width at half maximum (FWHM).

Nonlinear optics at nanoscale is a recent fascinating research field. Among the numerous nonlinear optics phenomena, stimulated Raman scattering is one of the most interestingphenomena, due to its significant implications from both fundamental and applicative point of view. In this paper, the observations of stimulated Raman scattering, at the wavelengths of interest for telecommunications, in silicon nanocomposite and in amorphous silicon nanoparticles are reported. A significant Raman gain enhancement and a significant threshold power reduction with respect to silicon are demonstrated. Our findings indicate that nanostructured materials show great promise for Si-based Raman lasers.
