A chirped continuum, generated in a photonic bandgap fiber by 120 fs Ti:Sapphire laser pulses, is parametrically amplified in a BBO crystal pumped by an injected and frequency doubled nanosecond Nd:Yag laser pulse. Without changing the frequency of the Ti:Sapphire, a spectral tunability of the amplified pulses is demonstrated. The possibility to achieve broader spectral range amplification is demonstrated for a non-collinear pump-signal interaction geometry.
