A gain switch semiconductor laser diode was used as the seed source, and a multistage single mode Ybdoped fiber preamplifier was combined with two large mode area doubleclad Ybdoped fiber main amplifiers to construct the amplification system. The tunable pulses with high stability and excellent beam quality (M2</abstract> <index>Open Science Index 40, 2010</index> </article>
