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.
