摘要：

We propose a novel mechanical method tp produce laser pulses. The laser cavity includes two pieces of fibers, and at least one of them is active fiber acing as gain medium. A piezo-electric actuator is utilized to modulate the transmitted power between the fibers, and thus changed the round-trip loss in the fiber laser cavity Q-switching pulses are successfully achieved up to the repetition rate of 10 kHz. Output pulses with 412 ns width and 10 mW average power are obtained at 200 Hz repetition rate.
