The authors report stable short high-repetition-rate Q-switched pulses in acousto-optic Q-switched ytterbium-doped double-clad fiber lasers. This device uses a diode pumped at 975 nm to end pump the large mode area double-clad fiber laser. In the experiment acousto-optic modulator is used as a special Q-switching in the F-P cavity. As a result, sub 100 nanosecond pulses are obtained with varying the acoustic-optic repetition rate from 1 kHz to 100 kHz. The Q-switching technique provides a novel method to generate short pulses at high repetition rate.
