“…igh-power narrow linewidth (NL) fiber amplifiers with linearly polarized have earned a solid reputation due to their remarkable capacity in gravitational wave detection (GWD), nonlinear frequency conversion (NFC), spectral beam combining (SBC) and coherent beam combining (CBC) [1]- [5] etc. By taking into the various strategies of seed sources, some conventional methods to realize high-power NL linearly polarized fiber amplifiers are to use phase modulated single-frequency laser (PMSFL) seeds [6], [7], superfluorescent (SF) seeds [8], random fiber laser (RFL) seeds [9] and fiber oscillator laser (FOL) seeds [10]- [13]. Over the last few years, many excellent works have been achieved.…”

A gain-enhanced 10/125 µm polarizationmaintaining Yb-doped fiber (PMYDF), with the cladding absorption of 7.5 dB/m at 976nm, for narrow linewidth linearly polarized fiber oscillator or amplifiers is presented. By utilizing the gain-enhanced PMYDF in an all-fiber laser oscillator, an output power of 123 W is achieved with applying appropriate bending strategies and thermal management, corresponding to the slope efficiency of 86.7%. By applying the gain-enhanced PMYDF in seed, an increase of 34% in the longitudinal mode interval is effectively achieved compared to the commercial PMYDF, while the number of longitudinal modes is only 75%. According to the main oscillation power amplification (MOPA) system, the total amount of spectral broadening applying the seed with the gainenhanced PMYDF are only 67%, 64% and 54% of applying the seed with the commercial PMYDF, corresponding to co-pumping, bi-pumping and counter-pumping schemes, respectively.
