摘要
从最基本的耦合波方程出发,考虑光波正反向传输的情况下,推导出了一个全面的、准确的关于连续级联喇曼光纤激光器的理论模型,描述了各级Stokes光波功率沿光纤长度的变化.指出了相关一些文献中存在的不足,并且给出了多级斯托克斯光波相互作用的有效作用面积的表达式.此模型有助于喇曼光纤激光器的设计.
A comprehensive and accurate numerical model is presented based on basic coupled equations to describe multi-Stokes Raman lasing performances in optical fibers. Though much work has been done on this, there are insufficiencies and shortcomings more or less in the literatures after analysis of them. These insufficiencies are also pointed out in this paper. The interactions between forward and backward traveling waves together with interactions between Stokes at different orders are all taken into account in this model. Effective core area for the interaction between multi-Stokes has also been obtained. The numerical solution of the differential system will lead in a natural way to calculate Stokes powers at the output end of the fiber. The proposed model is important for the design of CW cascaded Raman fiber lasers.
