Abstract：
We demonstrated an all-fiber single-frequency DBR master oscillator and power amplifier at 1992.6 nm. The maximum output power of the fiber amplifier was 100 W with a slope efficiency of 53% and the optical signal-to-noise ratio was about 50dB. The linewidth was less than 66 kHz and the beam quality factor M-2 was 1.22 at the maximum output power. The RINs of the seed and the power amplifier were measured to be -120 dB/Hz and -102 dB/Hz at the relaxation oscillation frequency, respectively.
