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. Supperted by National Natural Science Foundation of China (No. 60477022)
