摘　　要：对国产掺镱(Yb3+)双包层大模场面积光纤超短脉冲放大器进行了系统的实验研究。以自己搭建的脉冲宽度为2.3ps,重复频率为95MHz的全固态锁模激光器作为种子源,以976nm大功率光纤耦合激光二极管为抽运源,以1.6m国产掺Yb3+双包层大模场面积光纤为增益介质,在11.2W的入纤抽运功率下,将平均功率为100mW的脉冲种子光放大到平均功率2.41W,单脉冲能量达到了25nJ,放大后脉冲的宽度(时域宽度)和光谱都有所展宽。The experimental study on an ultrashort laser amplifier using a domestic Yb^3＋-doped large-mode-area fiber as gain media was presented. The seed pulse has a width of 2.3 ps and repetition rate of 95 MHz, provided by an all-solid-state mode-locking laser designed by ourselves. The pump source is a 976 nm fiber-coupled laser diode （LD）. The output pulse with the average power of 2.41 W from the 1.6 m gain fiber is achieved under the input pump power of 11.2 W, while the seed pulse average power is 100 mW. The amplified energy per pulse is up to 25 nJ. The width of the pulse is broadened from 2.3 ps to 3.0 ps, synchronously.
