The Ti:sapphire Optical Parametric Amplifier was applied as the pump source with the output wavelength tuning.Supercontinuum generation in photonic crystal fibers was researched with different pump wavelengths.It was concluded that the SC generation was depended on the pump wavelength,and the difference group velocities in the two sides of the zero dispersive wavelength of the PCF and the OH absorption at about 1.4 μm in the PCF affected the flatness of the generated supercontinuum.When the pump wavelength lied further away from the zero dispersive wavelength,the flatness was reduced,even in the visible region the blue-shift peaks were separated and didnot come into being supercontinuum.Supercontinuum with a broad bandwidth of 300 nm to 1350 nm was generated with the pump wavelength of 1.2 μm,and the generated spectral bandwidth was beyond two octaves.
