摘要：
A novel acousto-optic switch operation by a simple laser-diode pumped acousto-optic, Q-switched, ytterbium-doped, double-clad fiber laser is reported. Stable compressed Q-switched sub-40 ns pulses with a beam quality factor (M-2 = 2) are achieved at the repetition rate of 1-50 kHz. Q-switched pulses of similar to 20 mu J pulse energy and 35 as pulse width are obtained at the repetition rate of 50 kHz. Finally, a reasonable explanation of the novel Q-switched operation is presented. (c) 2007 Optical Society of America.
