摘要：

We demonstrated, for the first time to our best knowledge, an active tapered double clad fiber with circular birefringence and 35 mu m core diameter. The output radiation had perfect beam quality (M-2=1.18/1.1) and linearly polarized light with 15 dB of PER. The developed double clad active fiber was investigated for amplification of picosecond pulses in all fiber MOPA system. The MOPA system delivered 50 ps pulses with 55 W of the average power revealed 34.4 dB gain of the booster amplifier.
