AB Fiber optical parametric amplifiers (FOPAs) have attracted considerable attention during the last decade because of theirbroad bandwidth, high gain and wavelength-flexibility. In comparison to cumbersome bulky systems, they bring theadvantages of all-fiber systems, i.e. reliability, long-term stability and compactness. FOPAs rely on the third-ordersusceptibility and are characterized by a quasi-instantaneous nonlinear response that involves pump, signal and idlerwaves. Chirped pulse amplification (CPA) allows to get a high energy amplification and its realization in FOPAs wouldincrease the overall performances of these amplifiers. Such an experimental demonstration has never been reported in thepast. In this work, we show for the first time the experimental feasibility of fiber-based optical parametric chirped pulseamplification (FOPCPA) with an all-fibered setup. The stretching/compression stages are realized with a single linearlychirped fiber Bragg grating (LCFBG) used in both directions while the amplification is performed in a CW-pumpedFOPA that uses 500 meters of highly nonlinear fiber (HNLF). Fourier transform limited optical pulses at 1550 nm arestretched from 6 ps to 70 ps and then amplified by 22 dB without any spectral or temporal distortions. Experiments areconfirmed by simulations carried out by numerical integration of the nonlinear Schrödinger equation with parametersmatching those of the experimental setup. For simplicity, this first experimental demonstration is realized in thetelecommunication window. By using photonic crystal fibers, one can move the working wavelength around 1 μm.
