7 May 2013Determination of amplifying parameters of LMA Yb:silica fiber amplifier
In this work, an exact numerical analysis has been made for rate equations of continuous-wave (CW) cladding-pumped
fiber amplifier. A comprehensive form is considered including the pump coupling efficiency, splice points and scattering
losses.
Moreover, we have focused on determination of the small-signal gain and the saturation power for a typical single-stage
large-mode area (LMA) Yb-doped silica fiber amplifier based on the steady-state amplification relation. The dependency of
those parameters to the pump power is investigated which is significantly due to the signal power filling factor.
