Abstract

Visible to near-infrared, widely broadened supercontinuum generation is demonstrated using an ultrashort-pulse fiber laser system. A $229\mathrm{mW}$, $83\mathrm{fs}$ high-power ultrashort pulse was generated at $1550\mathrm{nm}$ in an Er-doped fiber-chirped pulse amplification system. An almost pedestal-free $107\mathrm{fs}$ second-harmonic pulse was generated at $780\mathrm{nm}$ using periodically poled $\mathrm{Li}\mathrm{Nb}{\mathrm{O}}_3$. A $0.45–1.38\mu \mathrm{m}$ widely broadened supercontinuum was generated in a highly nonlinear photonic crystal fiber. In terms of spectral flatness, the total modulation bandwidth was within $14\mathrm{dB}$. All of the fiber devices were fusion spliced so that the system showed good stability. The effect of a pulse-trapping phenomenon in the supercontinuum generation process was discussed from experimental considerations.
