The characteristics of acoustic-optic double-clad fiber laser end-pumped by diode laser are reported for different pumping constructions. The comparison and discussions of average power, pulse width and stability of Q-switched pulses under the forward pump and back ward pump conditions are presented. In experiment, the output of Q-switched pulses with 60% slope efficiency of average power, 52ns pulse width and 03mJ single pulse were obtained at the repetition rate of 10kHz. Finally, the rate equations with different pump configurations are deduced to analyze the Q-switched pulse, and the theoretical results agree with well experimental results.
