Abstract

From the propagation equations of Yb3+-doped fiber amplifiers, the characteristics of Yb3+-doped double-clad fiber amplifier for 1053 nm pulse amplification are comprehensively analyzed through finite-difference method based on numerical modeling. The steady distributions in the fiber of the upper-level population, pump power, and amplified spontaneous emission with 977 nm forward pumping are calculated. The single pulse waveform distortion after amplification is analyzed. Modeling attains a special input waveform which can deduces the super-Gauss type output after pulse amplification. The most suitable fiber length and the impacts of forward pumping and backward pumping are also discussed.
