Supercontinuum generation pumped by a regeneratively mode-locked fiber laser

Abstract

Supercontinuum (SC) generation in a dispersion-shifted fiber (DSF) pumped by a 10 GHz regeneratively mode-locked fiber laser (RMLFL) is presented. Optimization of pump wavelength leads to a 20 dB bandwidth of 58. 73 nm, which covers the whole C band and part of L band. Using an angle-tuning thin film filter, multi-wavelength and pico-second pulse trains of low chirp could be chosen from the SC spectrum. Amplified spontaneous emission(ASE) induced degeneration of the achieved pulse trains is observed and discussed.
