An acousto-optically Q-switched frequency-shifted feedback (FSF) diode-pumped laser with a Nd:YVO(4) crystal is demonstrated. The laser emits more than 1W average power with multi-ten ns duration at up to 50 kHz repetition rate, and peak power higher than 1 kW is achieved at frequency of 20 kHz. This kind of pulsed laser has special value for some applications with outstanding features of broadband continuous spectrum and chirping frequency in the oscillation spectrum. Simulation results of the FSF laser through rate equations in Q-switched regime are also presented.
