摘要：

A　pulsed　acousto-optic　Q-switched　all-fiber　laser　in　master-oscillator　power　amplifier　(MOPA)　configuration　is　reported.　The　seed　source　is　using　LD　as　pump　source,　ytterbium-doped　fiber　as　the　gain　medium,　fiber　Bragg　grating　(FBG)　as　resonator　mirrors,　acousto-optic　Q-switch　(AOM)　as　a　modulator.　The　output　of　seed　source　is　amplified　by　two　stage　amplifier.　The　second　stage　amplifier　obtains　the　pulses　of　10　W　average　power,　10-34　kHz　repetition　rate,　1064　nm　center　wavelength.　When　the　repetition　rate　is　23　kHz,　the　pulse　width　is　275　ns　and　the　3　dB　spectral　width　is　2.492　nm.　©　OSA/SumSession　2011.
