We demonstrate a record high CW output power of 11.6 W and an ultra-narrow linewidth of 6 kHz in an all-fiber master oscillator and power amplifier (MOPA) fiber laser system. The master oscillator is a (13)C(2)H(2) frequency-stabilized single-polarization fiber laser with a 100 mW output. The power amplifier section consists of a core-pumped polarization-maintained erbium-doped fiber pumped by a 1480 nm cascaded Raman fiber laser. A total electric-to-optical conversion efficiency with a record high value of 12% was achieved with an all-fiber configuration.
我们展示了全光纤主振荡器功率放大器（MOPA）光纤激光系统中创纪录的11.6 W连续波输出功率和6 kHz的超窄线宽。主振荡器是一个输出功率为100 mW的（13）C（2）H（2）频率稳定单偏振光纤激光器。功率放大器部分由一个由1480 nm级联拉曼光纤激光器泵浦的纤芯泵浦保偏掺铒光纤组成。采用全光纤配置实现了创纪录的12%的高电光转换效率。
