Abstract
In order to study the stimulated Brillouin scattering ( SBS) effect on the pulse form of pulsed fiber laser amplifiers, a single frequency fiber laser amplifier system was built and its pulse waveform distortion was observed in the experiment. If continuing to improve pump power, a high power spike appeared at the distorted location, which was induced by the second-order SBS effect in a fiber. To verify this conclusion, the coupled equations contains the second-order Stokes wave were built and simulated and the results showed that the high peak power spike was the second-order Stokes wave of SBS effect.关键词
