Numerical simulation of supercontinuum generation in all-fiber Er-doped master oscillator fiber amplifier

Numerical study based on nonlinear Schrodinger equation was conducted to optimize the characteristics of all-fiber master oscillator fiber amplifier based on erbium-doped fiber laser. The generation of supercontinuum in high-nonlinearity fiber (HNLF) was achieved. The optimization of HNLF length, and the average power of amplified pulses led to 1155 nm spectral width at -20dB.
