| 摘 要： | 搭建了一台主振荡功率放大（MOPA）结构的窄线宽全光纤激光器。利用噪声相位调制技术将单频激光线宽展宽至0.3 GHz，通过四级放大器结构对10 mW的窄线宽种子激光进行放大，获得了功率为666 W的窄线宽激光输出。该窄线宽激光器输出功率仅受限于泵浦功率，增加泵浦功率有望进一步提高输出功率。

| Abstract: | A master oscillator power amplifier (MOPA) structured narrow-linewidth Yb-doped fiber laser is set up in all-fiber format. In the system, a single frequency laser is broadened to be a 0.3 GHz-linewidth seed by using noise phase modulation technique. The power of the seed is then scaled from 10 mW up to 666 W through a four-stage power amplifier chain. Further power-scaling of this MOPA system can be expected since our experiment is only pump-power limited. |
