| 摘 要： | 搭建了一台主振荡功率放大（MOPA）结构的单频脉冲全光纤激光器。通过对线宽为 20 kHz 的连续单频激光器进行强度调制，获得了重复频率 10 MHz、脉宽约 8 ns、平均功率约 0.5 mW 的单频脉冲种子激光。采用多级掺镱光纤放大器对脉冲种子激光进行级联放大，获得了平均功率 300.8 W 的高功率激光输出。目前，激光器输出功率仅受限于泵浦功率，有望通过增加泵浦功率进一步提高输出功率。

| Abstract: | A master oscillator power amplifier(MOPA) structured pulsed Yb fiber laser is set up. The single-frequency pulsed seed, with a repetition rate of 10 MHz, a pulse duration of about 8 ns, and an average power of 0.5 mW, is obtained by externally modulating a continuous wave laser with line width of 20 kHz. The pulsed seed is amplified to 300.8 W of average power with four Yb-doped fiber amplifiers. Further power-scaling of this MOPA structure can be realized since our experiment is only pump-power limited. |
