Influence of optical loss on nonlinear effect in stimulated Raman scattering system

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.
