A picosecond double-pass periodically poled KTiOPO4 (PPKTP) noncollinear parametric amplifier that delivers tunable and narrowband outputs between 1.1 mu m and 1.65 mu m is reported. The seed source is an ultra-broadband emitting PPKTP collinear parametric generator, which is spectrally narrowed, from a bandwidth of 80 THz to about 0.3 THz, by a Fourier-filtering arrangement. A parametric gain of 70 dB is measured with preserved spectral bandwidth, resulting in a signal energy of 6.5 mu J at a pump energy of 60 mu J from the Ti:sapphire regenerative amplifier. The total energy-budget for the setup is less than 100 mu J with an optical-to-optical efficiency of 12%. This particular system is scalable to even lower pump energies by tighter focusing arrangements
