Abstract
By considering propagation equations of Stokes-waves for different orders of the stimulated Brillouin scattering (SBS) and the stimulated Raman scattering (SRS) together with propagation-rate equations of Ytterbium-doped double-clad fiber amplifiers, we numerically analyze steady-state characteristics of these amplifiers such as Amplified Spontaneous Emission (ASE) and threshold pump power and parameters which have influence over it such as pumping configuration, pumping wavelength, input signal wavelength, input signal power, input signal bandwidth and amplifier geometry. Also in an experimental setup threshold pump powers under both forward and backward pumping configurations are measured. Our results are of prime importance for applications such as nonlinear frequency generation.
