摘要：

A piezoelectrically deformable output-mirror was used for the mechanical Q-switching of a laser-diode-pumped Nd3+:YVO4 microchip laser. A unimorph structure consisting of a piezoelectric polymer and a polymeric multilayered mirror on a flexible polymer substrate was vibrated to periodically change the laser-cavity loss under the application of an AC voltage of 250 V. It yielded Q-switched pulses with a duration of 16 ns at a repetition rate of 1.338 kHz for a pump power of 284 mW and a cavity length of 16 mm. The average power and peak power were 1.1 mW and 52 W, respectively.
