MARTINEZ RIOS, A. et al. Analytical approach for the design of cascaded raman fiber lasers. Rev. mex. fis. [online]. 2005, vol.51, n.4, pp.391-397. ISSN 0035-001X.

An analytical approach for the design of cascaded Raman fiber lasers is presented. The model computes the values of the pump and Stokes powers at the fiber laser output based on the boundary conditions, the invariants resultanting from the analysis of the coupled differential equations, and assuming that the sum of the forward and backward Stokes waves resonated inside the cavity is constant. The model is applied to Raman fiber lasers based on five nested cavities and compared with published results based on numerical models obtaining a good correlation.
