High power all-fiber amplifier with different seed power injection.

We report a high power all-fiber amplifier with suitable seed power injected by an all-fiber laser. Different seed powers were injected into the all-fiber amplifier during our amplification experiments, and we found the stimulated Raman scattering (SRS) threshold was inversely proportional to the injected seed power. More than 3 kW signal light with good beam quality (M2 = 1.28) has been obtained with a suitable seed power injected, and the slope efficiency of the all-fiber amplifier was about 84.4%.
