Abstract
An acousto-optic Q-switched pulse fiber laser was presented, and the output power of 20.3W was obtained by using the one-stage Ytterbium-doped double-cladding fiber amplification. The repetition frequency of the pulse fiber laser was tunable in the range of 20-60kHz. We obtained the pulse output with pulse width of 113ns, peak power of 9kW and the average power of 20.3W, when the repetition frequency was 20kHz. We also measured pulse width at different repetition rate and analyzed pulse waveform.
