Simulations of the Raman and Brillouin efficiencies versus the fiber length for a constant \( \gamma ={g}_R^f\ {P}_{Peak}\;L/{A}_{eff} \) product. The dashed red line corresponds to the Raman conversion efficiency taking into account Brillouin effect. The blue full line corresponds to the Brillouin conversion efficiency taking into account Raman effect. The dotted black line corresponds to the Raman conversion efficiency if the Brillouin gain is set to 0. The brown dot-dashed line stands for Brillouin efficiency in case the Raman gain is zero
