摘要：

We report experimental results on an all-fiberized linearly polarized single-mode pulse Yb-doped fiber laser/amplifier working at 1064 nm. Using a fiberized acousto-optic Q-switched ytterbium fiber laser as the seed source, a double-clad polarization-maintaining fiber as the gain medium, a (6+1) x 1 multimode pump combiner to input the seed signal and the pump power, an Yb fiber master oscillator power amplifier (MOPA) is demonstrated. It delivers a linearly polarized pulsed laser output working at 1064 nm with an average power of 30 W, a repetition rate of 40 kHz, a pulse duration time about 30 ns, a polarization extinction ratio greater than 10 dB, and a beam quality factor (M-2) of 1.36. Our experiments were pump-power limited and considerable scope remains for further power-scaling of such fiber MOPA using this approach.
