Evolution of the nth Stokes due to SRS in single mode fibers

In this work, the evolution of the nth analytical solutions of traditional Raman equations including numerical simulation and experimental results is done. In the experiment an 8.6 Km single mode fiber was pumped with an ytterbium doped fiber laser system (FL) in CW regime at 1064-nm in a free running configuration. We showed that it is possible to obtain up to the nth power thresholds and maximum power for each Stokes by using compact analytical solutions such as first approximations in an arguably simple, quick process.
