Visible to near-infrared widely broadened super continuum generation is demonstrated using ultrashort-pulse fiber laser system. Er-doped fiber chirped-pulse amplification system operated at 1550 nm in wavelength is used for the amplifier system, which generated ultrashort-pulse of 112 fs in FWHM with output power of 160 mW, on average. Almost pedestal free 200 fs second harmonic generation pulse is generated at 780 nm region using periodically poled LiNbO{sub 3} and conversion efficiency is as high as 37%. 0.45-1.40 {mu}m widely broadened super continuum is generated in highly nonlinear photonic crystal fiber and spectrum flatness is within {+-}6 dB. All of the fiber devices are fusion spliced so that this system shows a good stability.
