“…The SRS in the spectral region from 1.1-1.7 µm is of great importance in developing of several applications such as optical fiber communications, material processing, signal processing, laser spectroscopy and medicine [2]. Equations for the behaviour of the Raman amplification have been described [3,4] and solutions have been proposed [3,5]. Despite these advances, there are parameters such as maximum power stored in the Stokes signals, critical power for Raman lasers, and other parameters that have not been described.…”

This work present a methodology for estimating the maximum power stored in 1, 2,… orders Stokes. Analysis of the solution of equations that governing the stimulated Raman scattering is essential for the development of a novel mathematical relationship, which estimates with great approximation the maximum power stored in Stokes lines. The numerical simulations were tested experimentally for 9.6 km LEAF fiber, where it was found the theoretical maximum pumping power for the first Stokes was 2.4 W, while approximately 2.43 W was found experimentally. In other hand, for the second Stokes power was 4.695 W theoretically, while 4.1 W was found experimentally. The inaccuracy of estimation of optical conversion efficiency of the first Stokes was approximately 0.5%. While the second Stokes, the estimation error of the optical conversion efficiency was around 2.3%.Those results proof the consistency of the equations here reported.

“…), laser spectroscopy and medicine [3]. Equations for the behavior of the Raman amplification have been described in [4,5] and their solutions have been proposed in [4,6]. Despite these advances with the propagation equations describing the energy transfer among stokes components in Raman amplification, there is a lack of simple methods that allow the exact estimation of some important parameters such as: the Raman threshold power, the maximum pumping power necessary for the power stored in the Stokes signal to be maximized, the Raman gain coefficient and the power required to obtain any N-order of Stokes.…”

This work presents a methodology to estimate the pumping power required for the first Stokes to reach its maximum stored energy level, before it generates the next Stokes. These estimates are achieved by experimentally measuring the critical power and the relationship between the pumping power (PP0) and the small signal of the stimulated Raman spread (PF0). For our study we used 1 km of 1060-XP fiber, experimentally obtaining Pcr = 6.693 W, PF0/PP0 = 6.759x10−6. With these experimental data, the pump power required for the first Stokes to reach its maximum stored energy level was 13.39 W, and the stored energy in the first Stokes was 9.88 W. It is important to note that the Raman threshold ln(PP0/PF0) = 11.9 is smaller than the initially reported ∼16.

The evolution of the nth analytical solutions of commonly used Raman equations, analyzed by numerical simulation and experimentally, is reported. In the experiment, a 1 km undoped single-mode fiber was pumped with an ytterbium doped fiber laser system (FL) in continuous wave regime at 1064 nm in a free running configuration. We showed that it is possible to obtain up to the nth power thresholds and the maximum power for each Stokes wave by using compact analytical solutions as a first approximation in a simple, quick process. #
