摘要：

We demonstrate a pre-chirp managed amplification (PCMA) system that is based on two stages of core-pumped, polarization maintaining (PM) fiber amplifiers. It produces output pulses with <65 fs duration and >10 nJ pulse energy from single-mode fibers. Tailoring of the spectra in the amplification chain enables pulse compression to near-perfect transform limited pulses (Strehl-ratio >0.9) and low intensity noise levels (0.008%) despite B-integrals >40 rad in the PCMA amplifier. Design strategies are presented. We expect this PCMA system to become an easy to implement add-on to a variety of existing sources while maintaining the advantages of the robustness of the PM standard fiber format.
