Paper Abstract

In the paper, we reported a single-frequency(SF), single-mode(SM), linear-polarized ytterbium-doped all-fiber master oscillator power amplifier (MOPA) system consisting of two stage amplifier which could be used in coherent detection. With a pump power of 17.5W at 976nm, the system emitted up to 12.7 W of single-frequency radiation at a wavelength of 1064 nm with the polarization-extinction ratio (PER) more than 35dB and signal-to-noise ratio (SNR) more than 40dB. The final-stage amplifier operated with a high conversion efficiency of 73% and the gain of the whole amplifier achieved 31 dB, it has nearly diffraction-limited beam quality.
